Message:

Query: Don't attempt caching if running a WP_User_Query before plugins_loaded.

In #55594 user meta caching was enabled by default when making a WP_User_Query. Previously, this was only enabled if a developer specifically queried for 'all_with_meta'
fields. User meta caching is implemented using a pluggable function, cache_users. If a plugin runs a WP_User_Query before pluggable functions have been defined, this
will now cause a fatal error.

In this commit, a function_exists check is introduced to avoid calling cache_users if it's not defined. Additionally, a _doing_it_wrong notice is issued if the
WP_User_Query::query method is called before the 'plugins_loaded' hook.

Props carazo, subrataemfluence, oakesjosh, spacedmonkey, obenland, SergeyBiryukov, peterwilsoncc.
Fixes #56952.
