Message:

Posts, Post Types: Revert get_page_by_title()'s use of WP_Query.

Revert to legacy database query in get_pages_by_title(). Due to the lack of orderby clause in the previous database query, it is not possible to gain consistent results by converting the function to a WP_Query wrapper.

Reverts [54271, 54242, 54234].

Fixes #57039, #56991.
See #57041.
