This addresses a discrepancy where using `unlink()` allows for checking if it was successful via the return value, but `wp_delete_file()` did not have a return value, making it impossible to verify the result without doing overhead checks if the file still exists.
This also brings more consistency with the other `wp_delete_*()` functions, specifically:
* `wp_delete_file_from_directory()`
* `wp_delete_post()`
* `wp_delete_post_revision()`
* `wp_delete_attachment()`
* `wp_delete_attachment_files()`
* `wp_delete_comment()`
* `wp_delete_nav_menu()`
* `wp_delete_term()`
* `wp_delete_site()`
* `wp_delete_user()`
Includes adding basic unit tests for `wp_delete_file()`.

Sometimes errors only occur in unusual code paths such as the maintenance mode or installation screens. Due to lack of tests for these scenarios in core, such errors are usually only noticed very late. This change adds new end-to-end (e2e) tests to prevent regressions in the following areas:
- Maintenance mode (presence of a `.maintenance` file)
- Fatal error handler (simulated with an mu-plugin that causes an error)
- Installation screen (verifying full installation flow & that there are no database errors)
Thanks to these tests, an issue was already found and addressed in the default `wp_die` handler, as `wp_robots_noindex_embeds` and `wp_robots_noindex_search` used to cause PHP warnings due to `$wp_query` not existing.
In the future, these tests can be extended to also test scenarios like localized error pages via `wp_load_translations_early()`.

Replaces `trigger_error()` with `wp_trigger_error()`.
The usage of `wp_trigger_error()` avoids generating `E_USER` family errors unless `WP_DEBUG` is on. In doing so, users should not see these messages in normal production.
Notes:
* Removes `E_USER_NOTICE` when passed as an argumnent, as it's the default error level.
* An empty string is passed for the function name when its name is already in the error message or does not add value to the error message.
* Externally maintained libraries are not included.

There are several exist places in Core that attempt to detect if a blog charset
is UTF-8. Each place attempts to perform the same check, except the logic is
spread throughout and there's no single method provided to make this
determination in a consistent way. The `_canonical_charset()` method exists,
but is marked private for use.
In this patch the new `unicode` module provides `is_utf8_charset()` as a method
taking an optional charset slug and indicating if it represents UTF-8,
examining all of the allowable variants of that slug. Associated code is
updated to use this new function, including `_canonical_charset()`. If no slug
is provided, it will look up the current `get_option( 'blog_charset' )`.
Finally, the test functions governing `_canonical_charset()` have been
rewritten as a single test with a data provider instead of as separate test
functions.

Modify `is_wp_version_compatible()` to return the expected result for major WordPress versions formatted as either `x.x` or `x.x.0` (for example `6.5` and `6.5.0`).
The WordPress project currently documents major version numbers in both formats leading to confusion for developers using the `is_wp_version_compatible()` function. As the PHP function `version_compare()` treats `x.x` and `x.x.0` as different version numbers this leads to unexpected results in the WP function.
This change removes a trailing `.0` from major version numbers to account for the WordPress project using the two formats interchangeably.

When the fatal error handler is triggered within a REST API request, it currently utilizes wp_die to display a specially formatted error response. However, crucial information captured by the fatal error handler, such as the exact line where the error occurred, is not included in the response due to potential security concerns, such as leaking file paths.
To address this limitation and aid developers in debugging, this enhancement introduces the inclusion of error data in the response when the `WP_DEBUG_DISPLAY` constant is set to true. This additional data, appended under the new key error_data, will facilitate more thorough debugging for REST API errors.

This introduces a more lightweight library for loading `.mo` translation files which offers increased speed and lower memory usage.
It also supports loading multiple locales at the same time, which makes locale switching faster too.
For plugins interacting with the `$l10n` global variable in core, a shim is added to retain backward compatibility with the existing `pomo` library.
In addition to that, this library supports translations contained in PHP files, avoiding a binary file format and leveraging OPCache if available.
If an `.mo` translation file has a corresponding `.l10n.php` file, the latter will be loaded instead.
This behavior can be adjusted using the new `translation_file_format` and `load_translation_file` filters.
PHP translation files will be typically created by downloading language packs, but can also be generated by plugins.

This changeset introduces two functions:
* `wp_is_serving_rest_request()` returns a boolean for whether WordPress is serving an actual REST API request.
* `wp_is_rest_endpoint()` returns a boolean for whether a WordPress REST API endpoint is currently being used. While this is always the case if `wp_is_serving_rest_request()` returns `true`, the function additionally covers the scenario of internal REST API requests, i.e. where WordPress calls a REST API endpoint within the same request.
Both functions should only be used after the `parse_request` action.
All relevant manual checks have been adjusted to use one of the new functions, depending on the use-case. They were all using the same constant check so far, while in fact some of them were intending to check for an actual REST API request while others were intending to check for REST endpoint usage.
A new filter `wp_is_rest_endpoint` can be used to alter the return value of the `wp_is_rest_endpoint()` function.

Make layout support compatible with enhanced pagination by ensuring that generated class names are stable across pagination, even when the number of rendered posts is different.
With the previous implementation of enhanced pagination, the CSS corresponding to each block was not detected. Therefore, for enhanced pagination to work correctly, the CSS of the blocks present in the Post Template must be stable on all pages.
The number of posts rendered by the Query block is always the same, except in the last page, where it can be only a fraction. If any of the blocks rendered by the Post Template used the `wp_unique_id` function, the ID (which is incremental) would have been different than in the previous pages and the class names would have varied.
This is remediated by this changeset by replacing the usage of `wp_unique_id` in the layout support (which is used by the Query block) with an implementation that uses IDs that are incremental only for that block. That way, the generated class names are never affected by the number of times `wp_unique_id` runs.

In [53941], the addition of query caching to `WP_Query` brought about an unintended issue when querying for fields equal to id=>parent. Specifically, on websites with object caching enabled and a substantial number of pages, the second run of this query triggered the `_prime_post_caches` function for id=>parent. This led to the unnecessary priming of post, meta, and term caches, even when only id and parent information were requested.
This commit addresses this issue by introducing a new function, `_prime_post_parents_caches`, which primes a dedicated cache for post parents. This cache is primed during the initial query execution. Subsequently, the `wp_cache_get_multiple` function is employed to retrieve all post parent data in a single object cache request, optimizing performance.
Additionally, this commit extends the coverage of existing unit tests to ensure the reliability of the changes.

Uses `wp_kses()` instead of `esc_html()` to allow a list of HTML tags and protocols in the message rather than escaping them.
Why? To retain message readability in the browser and server logs, especially given that Core itself adds HTML to messages in functions, e.g. `_doing_it_wrong()` and each of the `_deprecated_*()` functions.
HTML tags allowed:
* `a href`
* `br`
* `code`
* `em`
* `strong`
Protocols allowed: `http` and `https`.
To inform extenders, it also documents that any other HTML tags or protocols need to be escaped before passing the message to this function to avoid them being stripped from the message.

Using script tag helper functions allows plugins to employ the `wp_script_attributes` and `wp_inline_script_attributes` filters to inject the `nonce` attribute to apply Content Security Policy (e.g. Strict CSP). Use of helper functions also simplifies logic in `WP_Scripts`.
* Update `wp_get_inline_script_tag()` to wrap inline script in CDATA blocks for XHTML-compatibility when not using HTML5.
* Ensure the `type` attribute is printed first in `wp_get_inline_script_tag()` for back-compat.
* Wrap existing `<script>` tags in output buffering to retain IDE supports.
* In `wp_get_inline_script_tag()`, append the newline to `$javascript` before it is passed into the `wp_inline_script_attributes` filter so that the CSP hash can be computed properly.
* In `the_block_template_skip_link()`, opt to enqueue the inline script rather than print it.

Introduces `wp_trigger_error()` as a wrapper around PHP's native `trigger_error()`. As a wrapper, it's lean and not opinionated about the message. It accepts an E_USER family error level, meaning it is not limited to only notices.
Where `_doing_it_wrong()` intends to loudly alert developers "Hey you're doing it wrong - fix it", `wp_trigger_error()` is not opinionated and does not add wording. Rather, it passes the given message to `trigger_error()`.
`wp_trigger_error()` is meant for every `trigger_error()` instance. It can be used:
* in `_doing_it_wrong()` and each `_deprecated_*()` function.
* for PHP 8.x deprecations.
* for PHP error parity.
* for less severe "doing it wrong" instance that do not require bailing out.
* when a component or extension is not available on the server
* for instances where it's not clear if a plugin's or theme's code is the root cause.
* and more.
Technical details:
* Does not trigger the error if `WP_DEBUG` is not `true`.
* Includes `wp_trigger_error_run` action to allow hooking in for backtracing and deeper debug.
* Accepts an E_USER error level, but defaults to `E_USER_NOTICE`.
* Requires a function name, though can be an empty string. As the output message generated by `trigger_error()` references the file and line number where it was invoked, passing the function's name provides more information where the error/warning/notice/deprecation happened. It's intended to help with debug.
* A WordPress version number is not included.
* As messages can appear in the browser, the message is escaped using `esc_html()`. As noted in [https://www.php.net/manual/en/function.trigger-error.php the PHP manual]: "HTML entities in message are not escaped. Use htmlentities() on the message if the error is to be displayed in a browser."

The transient `dirsize_cache` stores an array of directory sizes. This transient can grow very large, if the plugin directory has lots of sub directories in it. For example, a site with 30 plugins, the transient was around 2MB. For sites without a persistent object cache, transients without an expiration, are stored in autoloaded options. This means this option would load on every page request. Loading this option on every page request when it is not used it wasteful. Adding a expiration to this transient means it will not autoload. To ensure there is no degradation in performance, the expiration was set to a generous 10-year timeframe, making it highly unlikely to expire before it's refreshed.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.
This commit renames the `$class` parameter to `$class_name` in `_deprecated_class()`.
Follow-up to [54929], [56467].
