Media: Better handling of JOINs when searching filenames.

Following [38625], any media searches that already included JOINs,
e.g., `tax_queries`, would get trampled when we joined the post meta
table to search for filenames. This preserves existing JOINs and
also only applies the `_filter_query_attachment_filenames()` filter
when a search query is being performed.

Props flixos90, joemcgill.
Fixes #22744.
