Message:

Media: Bail early if image is already the requested size.

In WP_Image_Editor_Imagick, bail early in make_subsize() if the image is already the requested size. Previously, make_subsize() would create another copy of the file. WP_Image_Editor_GD doesn't have the same problem.

Props wojtekn, danielbachhuber.
Fixes #57370.
