Media: Add short-circuit filter to attachment_url_to_postid().

Browse Source 
Introduces the filter `pre_attachment_url_to_postid` to allow developers to short-circuit the function `attachment_url_to_postid()`.

The return values are expected to be an attachment ID, zero (`0`) to indicate no attachment was found or `null` to indicate the function should proceed as usual.

The function performs an expensive database query so developers making use of the function frequently may wish to use a custom table with appropriate indexes to reduce the load on their database server.

Props antpb, apermo, audrasjb, joedolson.
Fixes #61383.
