Scott Taylor 7eb24edf4e In wp_generate_attachment_metadata(), when an audio or video files contains upload-able image bits in its ID3 tags, only upload it if the image has not already been uploaded. Determine this by checking for a _cover_hash value in post meta that matches the md5 representation of the bits. ...

This prevents uploading an album of 10 songs and subsequently uploading 10 copies of the same album cover.

Props GregLone for the new filter/filter docs: `'attachment_thumbnail_args'`.
Fixes #27573.
