Message:

Networks and Sites: Lazy load site meta.

In [36566] a framework to lazily load metadata was introduced. This supported term and comment meta by default. In this commit, extends support for site ( blog ) meta. Site meta is not heavily used by core and is used by developers to extend multisite. In this change, _prime_site_caches and WP_Site_Query now call the new function wp_lazyload_site_meta. The function wp_lazyload_site_meta accepts an array of ids and adds them to the queue of metadata to be lazily loaded. The function get_blogs_of_user was updated to now lazily load site meta.

Follow on from [55671].

Props spacedmonkey, johnjamesjacoby, peterwilsoncc, mukesh27.
Fixes #58185.
