Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.
See #41452.

Prior to this change there were two different cache keys used for the same query. That is because regardless of the `$fields` argument, the query response will be the same. This was already fixed for `WP_Site_Query` in [41059].
Props spacedmonkey.

One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.
Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`
Props spacedmonkey, desrosj.

Hiding the `$wpdb` global behind a property decreases the readability of the code, as well as causing irrelevant output when dumping an object.
Reverts [38275], [38278], [38279], [38280], [38387].
See #37699.

Provides a consistent way to query `$wpdb->site` for `WP_Network` objects based on domain, path, network ID, and (main) site ID.
Introduces and uses update_network_cache() and _prime_network_caches() to maintain a cached list of WP_Network objects for use in multiple queries.
