ryan 295ca4d76f Introduce wp_cache_switch_to_blog() and WP_Object_Cache::switch_to_blog() as a lighter/faster way to switch the cache to a new blog id. 
Add the blog id to the cache keys for multisite installs.

Use wp_cache_switch_to_blog() instead of wp_cache_init() in switch_to_blog().

Use wp_cache_switch_to_blog() instead of wp_cache_reset() in wp_start_object_cache().

Deprecate wp_cache_reset().

This avoids the many queries needed to re-prime the cache after switch_to_blog() on multisite installs using the default cache backend.

fixes #21434

nacin 167124051b If $group is empty in WP_Object_Cache::decr(), consider it to be 'default'. 
This is consistent with the rest of the cache methods wrapped by
functions; the functions pass an empty string by default, hence
the need for this check.

props bananastalktome.
fixes #21327.
