Jeremy Felt 9fa38fdc31 Multisite: Introduce get_site()
Given a site ID or site object, `get_site()` retrieves site data in the same vein as `get_post()` or `get_comment()`. This will allow for clean retrieval of sites from a primed cache when `WP_Site_Query` is implemented.

Adds a `WP_Site::to_array()` method to support multiple return types within `get_site()`.

Props spacedmonkey.
See #35791.
