`str_contains()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) contains the given substring (needle).
WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `false !== strpos( ... )` with `str_contains()` in core files, making the code more readable and consistent, as well as better aligned with modern development practices.

When the logic to exclude images that likely appear above the fold from being lazy-loaded was introduced in WordPress 5.9, initially only images that appear within the main query loop were being considered. However, there is a good chance that images above the fold are rendered before the loop starts, for example in the header template part.
It is particularly common for a theme to display the featured image for a single post in the header. Based on HTTP Archive data from February 2023, the majority of LCP images that are still being lazy-loaded on WordPress sites use the `wp-post-image` class, i.e. are featured images.
This changeset enhances the logic in `wp_get_loading_attr_default()` to not lazy-load images that appear within or after the header template part and before the query loop, using a new `WP_Query::$before_loop` property.
For block themes, this was for the most part already addressed in [55318], however this enhancement implements the solution in a more generally applicable way that brings the improvement to classic themes as well.

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.

`str_starts_with()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins with the given substring (needle).
WordPress core includes a polyfill for `str_starts_with()` on PHP < 8.0 as of WordPress 5.9.
This commit replaces `0 === strpos( ... )` with `str_starts_with()` in core files, making the code more readable and consistent, as well as improving performance.
While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

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.
