`_wp_array_get()` is an expensive function, and it's called thousands of times on each page view on the front end. While the function performance was slightly improved in #58376, it is still called more times than it should be.
This commit aims to further optimize its usage:
* In many cases, `_wp_array_get()` can be replaced with a much simpler and faster `isset()` check.
* The `isset()` function is capable of checking nested arrays, so `isset( $foo['a']['b']['c'] )` will return false even if `$foo['a']` is unset, without throwing any errors or warnings.
* When `_wp_array_get()` cannot be directly replaced with `isset()`, it would be good practice to wrap it in an `isset()` function so that `_wp_array_get()` only runs when it needs to.

The `get_default_block_editor_settings()` function included several pieces of data that are irrelevant for the purpose that `WP_Theme_JSON_Resolver` was calling it for, yet resulted in three database queries on page load that can be avoided.
This changeset introduces a new function `get_classic_theme_supports_block_editor_settings()` to takes responsibility of only the data needed in `WP_Theme_JSON_Resolver`, which now uses that function. This leads to a reduction of database queries and accordingly a performance improvement.

Adds `wp_theme_has_theme_json()` for public consumption, to replace the private internal Core-only `WP_Theme_JSON_Resolver::theme_has_support()` method. This new global function checks if a theme or its parent has a `theme.json` file.
For performance, results are cached as an integer `1` or `0` in the `'theme_json'` group with `'wp_theme_has_theme_json'` key. This is a non-persistent cache. Why? To make the derived data from `theme.json` is always fresh from the potential modifications done via hooks that can use dynamic data (modify the stylesheet depending on some option, settings depending on user permissions, etc.).
Also adds a new public function `wp_clean_theme_json_cache()` to clear the cache on `'switch_theme'` and `start_previewing_theme'`.

Here's what it does:
* Do not load and parse `theme-i18n.json` schema if the theme does not have a `theme.json` file.
* Fix the variable caching layer around the theme's `theme.json` parsing so that a parent's theme `theme.json` is cached as well.
* Do not run a `WP_Query` for global styles for a user when the theme does not have a `theme.json`.
In a basic WordPress setup, this changeset improves `wp_head` execution time for classic themes by 10%, and overall response time for both block themes and classic themes by 4%. This may seem like a small win, but 4% reduced overall response time is actually quite a bit for one change, and it is worth mentioning that this is just one of several other little performance tweaks which are being worked on to improve performance of `theme.json` parsing further.

A significant performance regression was added late in WP 6.1 beta cycle when some of the existing caching for `theme.json` processing was removed. The rationale for removing the caching was this code was now used before all the blocks are registered (aka get template data, etc.) and resulted in stale cache that created issues (see [https://github.com/WordPress/gutenberg/issues/44434 Gutenberg Issue 44434] and [https://github.com/WordPress/gutenberg/issues/44619 Gutenberg Issue 44619]). The changes were limited to only reads from the file system. However, it introduced a big impact in performance.
This commit adds caching and checks for blocks with different origins. How? It add caching for the calculated data for core, theme, and user based on the blocks that are registered. If the blocks haven't changed since the last time they were calculated for the origin, the cached data is returned. Otherwise, the data is recalculated and cached.
Essentially, this brings back the previous cache, but refreshing it when the blocks change.
It partially adds unit tests for these changes. Additional tests will be added.

This changeset updates the blocks origin name from core to blocks and adds it to the list of valid origins for `theme.json`.
(See the original fix in [https://github.com//pull/3319 Gutenberg's PR 44363]).
Why?
- This new origin was missing from the list.
- The `core` name is not reflective of what it does, as this data origin is related to block styles, whether they come with WordPress or third-party blocks.
- The existing filter for this piece of data is called `theme_json_blocks`, to reflect it filters "block" data.
- Though `core` origin was used in the past for `default`, this commit reverts it. Why? It was confusing. The goal is to use names that communicate what part of the pipeline are processing (`default > blocks > theme > custom`).
How?
- Renames the string, from `core` to `blocks`.
- Adds `blocks` to the list of valid origins.
- Verifies that the `$theme_json->get_stylesheet()` call uses the proper `$origins` at all times.

Also, to prevent any performance degradation by the removal, the file contents of `theme.json` files are now cached in `WP_Theme_JSON_Resolver::read_json_file()`, preventing multiple filesystem reads.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.
