This fixes the "Deprecated: Return type of `WP_Hook::[METHODNAME]()` should be compatible with `ArrayAccess::[METHODNAME](): type`" warnings on PHP 8.1.
PHP native interfaces now have declared return types and methods in classes implementing these interfaces need to either have the return type declared (in a covariant compatible manner with the PHP native interface method declaration), or need to silence the deprecation warning using the `#[ReturnTypeWillChange]` attribute.
Follow-up to [51517], [51529].
Props jrf.

Use `$hook_name` when referring to a filter or action hook name, and `$callback` when referring to a callback function.
This brings more consistency to parameter names in Plugin API functions.
Includes minor code layout fixes for better readability and reordering some functions in a more logical order.

Synchronize documentation for `add_filter()`, `tests_add_filter()`, `_wp_filter_build_unique_id()`, `_test_filter_build_unique_id()`.
Add a note that `$tag` and `$priority` are no longer used in `_wp_filter_build_unique_id()` since [46220], and the function always returns a string now.

This tag has been used in the past, but should no longer be used. Just using the `static` keyword in code is enough for PhpDocumentor on PHP5+ to recognize static variables and methods, and PhpDocumentor will mark them as static.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

Filters and actions have been the basis of WordPress' plugin functionality since time immemorial, they've always been a reliable method for acting upon the current state of WordPress, and will continue to be so.
Over the years, however, edge cases have cropped up. Particularly when it comes to recursively executing hooks, or a hook adding and removing itself, the existing implementation struggled to keep up with more complex use cases.
And so, we introduce `WP_Hook`. By changing `$wp_filter` from an array of arrays, to an array of objects, we reduce the complexity of the hook handling code, as the processing code (see `::apply_filters()`) only needs to be aware of itself, rather than the state of all hooks. At the same time, we're able te handle more complex use cases, as the object can more easily keep track of its own state than an array ever could.
