Media: Resolve fatal error on resize with ImageMagick < 6.4.6 

Improper checking for 'Imagick::ALPHACHANNEL_UNDEFINED' and
'Imagick::ALPHACHANNEL_OPAQUE' caused fatal errors for some users
with Imagick when compiled against ImageMagick < 6.4.6, when these
constants were introduced. Fixes these compatibility checks.

Merge of [37192] to the 4.5 branch.

Props gblsm.
Fixes #36501.
