Message:

Networks and Sites: Assign the array of site or network data returned from filters to the respective class property:

• The array of network data returned from the networks_pre_query filter is assigned to the networks property of the current WP_Network_Query instance.
• The array of site data returned from the sites_pre_query filter is assigned to the sites property of the current WP_Site_Query instance.

This avoids the performance overhead of calling WP_Network_Query::get_networks() or WP_Site_Query::get_sites() twice: first when creating the object instance, then to retrieve the filtered results.

This also makes the filters a bit more consistent with other similar filters, e.g. posts_pre_query, terms_pre_query, comments_pre_query, or users_pre_query.

Follow-up to [46086], [48990].

Props yakimun, spacedmonkey.
Fixes #51333.
