Multisite: Introduce a can_add_user_to_blog filter to prevent adding a user to a site.

Under certain circumstances, it can be necessary that a user should not be added to a site, beyond the restrictions that WordPress core applies. With the new can_add_user_to_blog filter, plugin developers can run custom checks and return an error in case of a failure, that will prevent the user from being added.

The user-facing parts and the REST API route that interact with add_user_to_blog() have been adjusted accordingly to provide appropriate error feedback when a user could not be added to a site. Furthermore, two existing error feedback messages in the site admin's "New User" screen have been adjusted to properly show inside an error notice instead of a success notice.

Props jmdodd.
Fixes #41101.
