This changeset implements a clearer and more consistent timeout/duration/expiration format. It updates time durations used in various files, as per WordPress coding standards:
- If the value can be represented as an integer (not a fractional) number of minutes (hours, etc.), use the appropriate constant (e.g.: `MINUTE_IN_SECONDS`) multiplied by that number.
- Otherwise, keep the value as is and add a comment with the units for clarity.

The existing filter `image_editor_output_format` receives an additional parameter `$size_name` which is populated whenever it controls the output format for a specific registered image size to create. Otherwise, it remains empty. In order to achieve this, a low level change has been added in bringing a new `$size_name` class property to the `WP_Image_Editor` base class, which is introduced in a backward compatible way that will not cause conflicts with custom implementations.
This parameter is then used in new logic inside the `wp_default_image_output_mapping()` callback function for the filter, controlling whether `image/jpeg` should map to `image/webp` output or not. By default, this is enabled for all WordPress core image sizes by default, and this list can be modified using a new `wp_image_sizes_with_additional_mime_type_support` filter, e.g. to remove core sizes or add custom sizes.
The customization per image size may be further enhanced by providing a more declarative API via a new parameter on the `add_image_size()` function.

This changeset adds a new `page_cache` check which determines whether the site uses a full page cache, and in addition assesses the server response time. If no page cache is present and the server response time is slow, the check will suggest use of a page cache.
A few filters are included for customization of the check:
* `site_status_good_response_time_threshold` filters the number of milliseconds below which the server response time is considered good. The default value is based on the `server-response-time` Lighthouse audit and can be altered using this filter.
* `site_status_page_cache_supported_cache_headers` filters the map of supported cache headers and their callback to determine whether it was a cache hit. The default list includes commonly used cache headers, and it is filterable to support e.g. additional cache headers used by specific vendors.
Note that due to the nature of this check it is only run in production environments.

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.
In this case, the `$use` property, as set in the class constructor, falls in the “known property” category.

This allows third-party themes to avoid accidentally being overwritten with an update of a theme of a similar name from the WordPress.org Theme Directory.
Additionally, introduce the `update_themes_{$hostname}` filter, which third-party themes can use to offer updates for a given hostname.
If set, the `Update URI` header field should be a URI and have a unique hostname.
Some examples include:
* `https://wordpress.org/themes/example-theme/`
* `https://example.com/my-theme/`
* `my-custom-theme-name`
`Update URI: false` also works, and unless there is code handling the `false` hostname, the theme will never get an update notification.
If the header is present, the WordPress.org API will currently only return updates for the theme if it matches the following format:
* `https://wordpress.org/themes/{$slug}/`
* `w.org/theme/{$slug}`
If the header has any other value, the API will not return a result and will ignore the theme for update purposes.

The function was using the `array_column()` PHP function on an array of objects, which works as expected on PHP 7 or later, but not on PHP 5.6.
This resulted in customized templates being listed multiple times on the Templates and Template Parts screens, and being repeatedly added between lists when switching between the screens.
The issue is now resolved by replacing `array_column()` with the `wp_list_pluck()` WordPress core function, which provides consistent behavior beetween PHP versions.

From [https://mariadb.com/kb/en/mariadb-1061-release-notes/ MariaDB 10.6.1 release notes]:
> The `utf8` [https://mariadb.com/kb/en/character-sets/ character set] (and related collations) is now by default an alias for `utf8mb3` rather than the other way around. It can be set to imply `utf8mb4` by changing the value of the [https://mariadb.com/kb/en/server-system-variables/#old_mode old_mode] system variable ([https://jira.mariadb.org/browse/MDEV-8334 MDEV-8334]).
From [https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-30.html#mysqld-8-0-30-charset MySQL 8.0.30 release notes]:
> **Important Change:** A previous change renamed character sets having deprecated names prefixed with `utf8_` to use `utf8mb3_` instead. In this release, we rename the `utf8_` collations as well, using the `utf8mb3_` prefix; this is to make the collation names consistent with those of the character sets, not to rely any longer on the deprecated collation names, and to clarify the distinction between `utf8mb3` and `utf8mb4`. The names using the `utf8mb3_` prefix are now used exclusively for these collations in the output of `SHOW` statements such as `SHOW CREATE TABLE`, as well as in the values displayed in the columns of Information Schema tables including the `COLLATIONS` and `COLUMNS` tables.
This commit adds `utf8mb3_bin` and `utf8mb3_general_ci` to the list of safe collations recognized by `wpdb::check_safe_collation()`. The full list is now as follows:
* `utf8_bin`
* `utf8_general_ci`
* `utf8mb3_bin`
* `utf8mb3_general_ci`
* `utf8mb4_bin`
* `utf8mb4_general_ci`
The change is covered by existing database charset unit tests: six tests which previously failed on MariaDB 10.6.1+ or MySQL 8.0.30+ now pass.
Includes:
* Adjusting the expected test results based on MariaDB and MySQL version.
* Using named data providers for the affected tests to make test output more descriptive.
* Adding a failure message to each assertion when multiple assertions are used in the test.
