Cache API: Introduce wp_cache_supports() function.

Browse Source 
WordPress has recently introduced a variety of caching API improvements:

* `wp_cache_add_multiple()`
* `wp_cache_set_multiple()`
* `wp_cache_get_multiple()`
* `wp_cache_delete_multiple()`
* `wp_cache_flush_runtime()`
* `wp_cache_flush_group()`

Although WordPress core provides a compatibility layer if these functions are missing from third-party object cache implementations, there should be a method of checking whether the cache backend supports a particular feature.

This commit aims to improve developer experience by allowing third-party object cache plugins to declare a `wp_cache_supports()` function and correctly list their supported features:

* `add_multiple`
* `set_multiple`
* `get_multiple`
* `delete_multiple`
* `flush_runtime`
* `flush_group`

Note: The `wp_cache_supports()` function replaces and supersedes the `wp_cache_supports_group_flush()` function added earlier.

Follow-up to [47938], [47944], [52700], [52703], [52706], [52708], [53763], [53767], [54423].
