Message:

Media: Automatically convert HEIC images to JPEG

Automatically create a JPEG version of uploaded HEIC images if the server has
a version of Imagick that supports HEIC. Conversion is done silently through
the existing WP_Image_Editor infrastructure that creates multiple sizes of
uploaded images.

This allows users to view HEIC images in WP Admin and use them in their posts
and pages regardless of whether their browser supports HEIC. Browser support
for HEIC is relatively low (only Safari) while the occurrence of HEIC images is
relatively common. The original HEIC image can be downloaded via a link on
the attachment page.

Props adamsilverstein, noisysocks, swissspidy, spacedmonkey, peterwilsoncc.
Fixes #53645.
