In [34270] introduced lazy loading of comment meta. However, this was only in the context of `WP_Query`. Other parts of the codebase, like `WP_Comment_Query` did not lazily load comment meta. In this change, calls to `update_meta_cache` are now replaced with `wp_lazyload_comment_meta`, that instead of priming comment meta caches, just adds them to the queue to be primed it ever called. This results in far less database queries, as there a number of places where comment meta is being primed unnecessarily and never used. Adding everything to the comment meta queue, also means that if comment meta is used, that is all loaded in a single database / cache call.

In the `fill_descendants` method in `WP_Comment_Query`, there is a loop the calls `wp_cache_get` to get `child comments. Instead of getting one key at a time, use `wp_cache_get_multiple` and get all keys at once.

Give developers more control over how query caches are handled within an object caches. Now all caches that cache the result of a query, are cached in a group that is suffixed with -queries. Developers can use these groups, to add custom cache invalidation rules or to make them none persistent.

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.

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 `$string` parameter to `$search` in `WP_Comment_Query::get_search_sql()`.

This avoids the performance overhead of calling `WP_Comment_Query::get_comments()` twice: first when creating the object instance, then to retrieve the filtered results.
This also makes the filter a bit more consistent with other similar filters, e.g. `posts_pre_query`, `terms_pre_query`, or `users_pre_query`.

This fixes a PHP 8 "argument must be passed by reference, value given" error when using `array_map( 'get_comment', ... )`.
Object variables in PHP 5+ contain a reference to the object, and it's the reference that's passed around.

The WP native `get_comment()` function expects the first argument `$comment` to be passed by reference.
The PHP `array_map()` function, however, passes by value, not by reference, resulting in an "arguments must be passed by reference, value given" error.
The PHP native `array_walk()` function does pass by reference. Using this prevents the error on PHP 8 and maintains the existing behaviour on PHP < 8.
