Subject: [PATCH] Tests: Move `wp_filesize()` tests to their own file.

This aims to make the tests more discoverable and easier to expand.

Includes splitting the `wp_filesize` and `pre_wp_filesize` filter tests into a separate test case.

Follow-up to [52837], [52932], [54402].

Props pbearne, spacedmonkey, SergeyBiryukov.
See #57171.
