Feature Request

In WordPress 6.1, wp_cache_flush_group was added to core. See blog post.

This function, allows for developers to clear all keys in a cache group, instead of one key at a time.

Describe the solution you'd like

Create a new command that allows for the wp_cache_flush_group function to be called, like so

wp cache clear group <group>

Before calling this function, if should check if the object cache support this functionality, by calling wp_cache_supports and fail fast if the current object cache doesn't support this functionality.
