Media: Store video creation date in meta.

When able to be parsed, store the created date for a video file from meta,
since this is useful separately from the dates on the file itself.

Introduces wp_get_media_creation_timestamp() to read the timestamp from
getID3 and a wp_read_video_metadata filter analogous to
wp_read_image_metadata.

Fixes #35218.
