When utilizing the `terms_clauses` or `get_terms_fields` filters within `WP_Term_Query` and the selected fields are modified, the entire term object is now cached. This adjustment is necessary because filters can broaden the selected fields beyond just the term ID. Fields linked to the term object, such as the count or parent, may undergo modifications when queried. Caching the complete object ensures the accurate storage of these modified fields within the cache.

In [34529] introduced lazy loading of term meta. However, this was only in the context of `WP_Query`. Other parts of the codebase, like `WP_Term_Query` did not lazily load term meta. In this change, calls to `update_termmeta_cache` are now replaced with `wp_lazyload_term_meta`, that instead of priming term 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 term meta is being primed unnecessarily and never used. Adding everything to the term meta queue, also means that if term meta is used, that is all loaded in a single database / cache call.

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.

Remove escape placeholder from query cache key, as placeholders are on a based on a unique id on every request. This meant that it is impossible for a cache to be reused, making queries that use escape placeholders such as searches, meta queries or using the `description__like` / `name__like` parameters were unable to be cached.

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.

Introduced [52836] when passing `child_of` or `pad_counts` parameters to `get_terms` or `WP_Term_Query` class, the array of terms received by the query, was not correctly cached. This
change simplifies the logic in `WP_Term_Query` and ensures terms are correctly cached. This change also, improves performance, by only caching an array of term ids where possible.

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.

The query cache currently implemented in `WP_Term_Query` caches the final output of the query, depending on what fields are requested. This is wasteful, as if a user requests `fields` => `all`, then an unlimited array of `WP_Term` objects could be stored in the object cache. Instead of storing the whole WP_Term object, this change only the term_id is stored. To get an array the full WP_Term objects, the `_prime_term_caches` function is called with an array of ids. In instances where a persistent object cache is not in use, then this will result in another SQL query to be run. After `_prime_term_caches` is called if this term is requested again in the same page load, then it will already be loaded into memory. If a user runs `WP_Term_Query` with the fields param set to `all_with_object_id`, an array of objects containing both the term_id and object_ids are stored in cache.
This change also improves the logic to load term meta caches. This change ensures that term meta is always primed for all terms loaded in the term query.

When querying for terms in hierarchical categories using `hide_empty=true`,
results have historically included parent terms which are themselves
unattached to any objects (are "empty") but which have non-empty descendent
terms. Because this process involves walking the descendant tree, we avoid it
when we detect that the queried taxonomies are not hierarchical. (This
behavior was introduced in [5525].)
When the `taxonomy` parameter of `get_terms()` was made optional - see #35495,
[36614] - it affected the mechanism for avoiding unneccessary tree walks,
since there may not be any explicitly declared taxonomies to run through
`is_taxonomy_hierarchical()`. As a result, term queries excluding `taxonomy`
did not check descendants, and empty parents with non-empty children were not
included in `hide_empty` results.
We correct the behavior by crawling term descendants when the `taxonomy`
argument is absent, which means that we're querying for terms in all taxonomies.
Props smerriman.
