After the introduction of `_make_clickable_rel_attr()` in an earlier commit, the function ended up returning link markup with a mix of single and double quotes.
This commit ensures that `_make_web_ftp_clickable_cb()` always returns double quotes, restoring consistency with other similar callback functions used by `make_clickable()`:
* `_make_url_clickable_cb()`
* `_make_email_clickable_cb()`

This changesets adds a `word_count_type` property, so that it does not need to be translated separately across multiple projects.
List of changes:
- New property: `WP_Locale::word_count_type`.
- New method: `WP_Locale::get_word_count_type()`.
- New function: `wp_get_word_count_type()` as a wrapper for `WP_Locale::get_word_count_type()`.
- All `_x( 'words', 'Word count type. Do not translate!' )` strings have been replaced with a call to `wp_get_word_count_type()`.

The `math` element can be displayed either as a block or inline element. If `wpautop` only treats it as an inline element, it will break multiline elements by inserting `br` elements. Treating the element as a block element means that the editor won't break common normative usages of the `math` element.
Prevent `math` elements from having internal elements split up with `br` elements, disrupting formatting.

This fixes a bug where if the `timezone_string` is set to a timezone name which has since been deprecated, the option value would be “lost” when saving the value again, as the comparison being done to verify whether it is a valid timezone name would only take “current” timezone names into account and would invalidate deprecated timezone names.
By passing the `DateTimeZone::ALL_WITH_BC` constant as the `$timezoneGroup` parameter to the PHP native `timezone_identifiers_list()` function, a timezone name list is retrieved containing both current and deprecated timezone names, preventing the invalidation of the option value.
See the extensive write-up about this in ticket #56468.
Also see: [https://www.php.net/manual/en/datetimezone.listidentifiers.php PHP Manual: timezone_identifiers_list()].
Includes adding a dedicated test to the data provider used in the `Tests_Option_SanitizeOption` test class.
Note: The new data set is ''named'', even though the other data sets are unnamed, to make sure it is clear what this data set is testing. Adding test names for the original data sets in this data provider would be a great future improvement, but is outside of the scope of this commit.

A general security rule is "Sanitize when you save, escape when you echo".
In WordPress 5.9, `sanitize_url()` was un-deprecated in order to better align with the naming of other sanitizing functions, while still being an alias for `esc_url_raw()`.
This commit reverses the order and turns `esc_url_raw()` into a wrapper for `sanitize_url()`, making the latter the canonical function call and aiming to improve performance by reducing the number of function calls required when using the recommended technique.

This is a follow-up to [52292] which introduced `is_string()` to check the given key is a string to be sanitized, else the key is set to an empty string.
`sanitize_key()` is clearly identified (in the documentation) to only work with ''string'' keys. However, it had a bug in it that allowed non-strings to pass through it:
* A non-scalar "key" would throw a PHP Warning (which was resolved in [52292].
* A non-string scalar "key" was handled by the PHP native `strtolower()` which converted it into a string.
While `is_string()` is valid, non-string scalar types passed as the key to be sanitized were being set to an empty string. Given that `strtolower()` handles these without error or deprecation as of PHP 8.1, `is_scalar()` protects the website from issues while retaining the past behavior of converting integer keys (for example) into a string.
Changes include:
* Using `is_scalar()` instead of `is_string()`
* Refactor for readability and less code
* More tests
Please note, this does not change the behavior of the function, nor redefine it to now accept non-string scalars.

As the `wp-emoji-loader.js` script is now included via `file_get_contents()` and `wp_print_inline_script_tag()` instead of `grunt-include` to simplify the logic, the task does not find anything to replace and is no longer necessary.

`sanitize_key()` expects a string type for the given `key`. Passing any other data type to `strtolower()` can result in `E_WARNING: strtolower() expects parameter 1 to be string, array given`.
A check is added that if the key is not a string, the key is set to an empty string. For performance, the additional string processing is skipped if the key is an empty string.

* Prevent loading `wp-embed` script unconditionally on every page in favor of conditionally enqueueing when a post embed is detected. The `wp-embed` script is also explicitly marked as being in the footer group. Sites which currently disable post embed scripts from being enqueued via `remove_action( 'wp_head', 'wp_oembed_add_host_js' )` will continue to do so.
* Send a `ready` message from the host page to each post embed window in case the `iframe` loads before the `wp-embed` script does. When the `ready` message is received by the post embed window, it sends the same `height` message as it sends when it loads.
* Eliminate use of `grunt-include` to inject emoji script and the post embed script. Instead obtain the script contents via `file_get_contents()` (as is done elsewhere in core) and utilize `wp_print_inline_script_tag()`/`wp_get_inline_script_tag()` to construct out the script. This simplifies the logic and allows the running of src without `SCRIPT_DEBUG` enabled.
* For the embed code that users are provided to copy for embedding outside of WP, add the `secret` on the `blockquote` and `iframe`. This ensures the `blockquote` will be hidden when the `iframe` loads. The embed code in question is accessed here via `get_post_embed_html()`.

This change prevents non-visible characters in titles from creating encoded values in permalinks, opting instead for the following replacement strategy:
* Non-visible non-zero-width characters are replaced with hyphens
* Non-visible zero-width characters are removed entirely
Included with this change are 64 additional PHPUnit assertions to confirm that only the targeted non-visible characters are sanitized as intended.
Before this change, URLs would unintentionally contain encoded values where these non-visible characters were. After this change, URLs intentionally strip out or hyphenate these non-visible characters.

This fixes `parse_str(): Passing null to parameter #1 ($string) of type string is deprecated` notices on PHP 8.1, without change in behaviour.
Impact: 311 of the pre-existing tests are affected by this issue.
The PHP native `parse_str()` function expects a string, however, based on the failing tests, it is clear there are functions in WordPress which passes a non-string – including `null` – value to the `wp_parse_str()` function, which would subsequently pass it onto the PHP native function without further input validation.
Most notable offender is the `wp_parse_args()` function which special cases arrays and objects, but passes everything else off to `wp_parse_str()`.
Several ways to fix this issue have been explored, including checking the received value with `is_string()` or `is_scalar()` before passing it off to the PHP native `parse_str()` function.
In the end it was decided against these in favor of a string cast as:
* `is_string()` would significantly change the behavior for anything non-string.
* `is_scalar()` up to a point as well, as it does not take objects with a `__toString()` method into account.
Executing a string cast on the received value before passing it on maintains the pre-existing behavior while still preventing the deprecation notice coming from PHP 8.1.

A general security rule is "Sanitize when you save, escape when you echo", and for the most part WordPress has well-named functions like `sanitize_email()` and others, with `esc_url_raw()` being a single exception that does not follow the naming.
This commit restores the previously deprecated `sanitize_url()` function as a valid alias of `esc_url_raw()`.
This better aligns with the naming with other `sanitize_*()` functions:
* `sanitize_bookmark()`
* `sanitize_bookmark_field()`
* `sanitize_category()`
* `sanitize_category_field()`
* `sanitize_comment_cookies()`
* `sanitize_email()`
* `sanitize_file_name()`
* `sanitize_hex_color()`
* `sanitize_hex_color_no_hash()`
* `sanitize_html_class()`
* `sanitize_key()`
* `sanitize_meta()`
* `sanitize_mime_type()`
* `sanitize_option()`
* `sanitize_post()`
* `sanitize_post_field()`
* `sanitize_sql_orderby()`
* `sanitize_term()`
* `sanitize_term_field()`
* `sanitize_text_field()`
* `sanitize_textarea_field()`
* `sanitize_title()`
* `sanitize_title_for_query()`
* `sanitize_title_with_dashes()`
* `sanitize_trackback_urls()`
* `sanitize_user()`
* `sanitize_user_field()`
