Message:

Media: Reset Exif orientation after rotate in WP_Image_Editor_Imagick.

Due to inconsistencies in the way browsers handle Exif orientation data,
if a user manually rotates an image within WordPress, set the Exif orientation to
the default (1) so that the image displays with the same rotation/flip in every browser.

See #14459.
Fixes #37140.
