These tests ensure that `wp_generate_attachment_metadata()` stores the file size of all newly uploaded attachments under the `filesize` array key. The tests were initially supposed to be committed with [52837].

Follow-up to [52837], [52932], [54861].

Props spacedmonkey, johnwatkins0, mitogh, adamsilverstein, pbearne, SergeyBiryukov.
Fixes #57171.
