Message:

Multisite: add new sites_pre_query and networks_pre_query filters to short circuit WP_Site_Query and WP_Network_Query queries.

Similar to the posts_pre_query filter for WP_Query added in #36687. These filters lets you short circuit the queries to return your own results.

Add a new filter sites_pre_query - which returns null by default. Return a non-null value to bypass WordPress's default get_sites queries.

Developers should note that filtering functions that require pagination information are encouraged to set the found_sites property of the WP_Site_Query object, passed to the filter by reference. If WP_Site_Query does not perform a database query, it will not have enough information to generate these values itself.

Add a new filter networks_pre_query - which returns null by default. Return a non-null value to bypass WordPress's default get_networks queries.

Developers should note that filtering functions that require pagination information are encouraged to set the found_networks property of the WP_Network_Query object, passed to the filter by reference. If WP_Network_Query does not perform a database query, it will not have enough information to generate these values itself.

Props spacedmonkey.
Fixes #45749.
