Message:

Cache API: Add wp_cache_flush_group function.

Add a new plugable function called wp_cache_flush_group, that will allow developers to clear whole cache groups with a single call. Developers can detect if their current implementation of an object cache supports flushing by group, by calling wp_cache_supports_group_flush which returns true if it is supported. If the developers of the object cache drop-in has not implemented wp_cache_flush_group and wp_cache_supports_group_flush, these functions are polyfilled and wp_cache_supports_group_flush defaults to false.

Fixes #4476.
