Joe McGill 04a88b9941 Grouped backports to the 5.8 branch.
- REST API: Limit `search_columns` for users without `list_users`.
- Comments: Prevent users who can not see a post from seeing comments on it.
- Application Passwords: Prevent the use of some pseudo protocols in application passwords.
- Restrict media shortcode ajax to certain type
- REST API: Ensure no-cache headers are sent when methods are overriden.
- Prevent unintended behavior when certain objects are unserialized.

Merges [56833], [56834], [56835], [56836], [56837], and [56838] to the 5.8 branch.
