 {{{
 #!CommitTicketReference repository="" revision="39588"
 Multisite: Handle capability check for removing oneself via
 `map_meta_cap()`.

 Site administrators should not be able to remove themselves from a site.
 This moves the enforcement of this rule from `wp-admin/users.php` to
 `remove_user_from_blog()` via the `remove_user` capability, which
 furthermore allows us to get rid of two additional clauses and their
 `is_super_admin()` checks in `wp-admin/users.php`. A unit test for the new
 behavior has been added.

 Fixes #39063. See #37616.
