In the past, `get_blog_details()` has been used to retrieve the `home`, `siteurl`, `blogname`, and `post_count` options for a site. By lazy loading properties in a `WP_Site` object, we can avoid having to use `get_blog_details()` and instead provide the properties as needed.
This introduces the global `site-details` cache group in which standard objects representing the site are stored. This will one day be a replacement for the `blog-details` cache group that is currently used in `get_blog_details()`.
This relies on the `ms_loaded` action introduced in [37916] as properties are not available via `get_option()` until multisite has been fully loaded.

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.

Given a network ID or network object, `get_network()` retrieves network data in the same vein as `get_site()` or `get_post()`. This will allow for clean retrieval of networks from a primed cache when `WP_Network_Query` is implemented.

In [37657], the `blog_id` and `site_id` properties were changed to private. Any `WP_Site` objects previously stored in cache with public properties should now be considered invalid. We can detect this by checking for these missing properties and clearing the dirty cache if found.

'comment' was made non-persistent in [7986], to address the difficulty of
reliable cache invalidation. Since then, the comment system has improved such
that we can be more confident that caches are being busted as needed.

Multisite functions use the term "blog" to refer to what we now call a "site," e.g. `get_current_blog_id()`. These functions are here to stay because of our commitment to backwards compatibility. What we can do is set the documentation straight.

* A `WP_Site` object initially matches a row from `wp_blogs`.
* A site can be retrieved by its ID through `WP_Site::get_instance()`.
* Adds `sites` to the global cache group and captures instance lookups.
* The multisite bootstrap now ensures `$current_blog` is an instance of `WP_Site`.

If `get_blog_details()` is returning something that is not our expected object or `false`, then a notice would already be thrown there.

In multisite, core expects the stored value for a site's path to have leading and trailing slashes. When these slashes are missing, it becomes impossible to visit the site.
This enforces proper `/path/` creation in `update_blog_details()`, most likely used when updating an existing site through `site-info.php`.
