Includes removing the `Normalizer::FORM_C` constant as a parameter, since it is the default value for both functions and does not need to be explicitly passed.

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.

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`.

* 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()`.

* 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.

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.

Add support for uploading, editing and saving WebP images when supported by the server.
Add 'image/webp' to supported mime types. Correctly identify WebP images and sizes even when PHP doesn't support WebP. Resize uploaded WebP files (when supported) and use for front end markup.
