[CI Filters] FEDropShadow in Core Image
https://bugs.webkit.org/show_bug.cgi?id=304871
rdar://167458159
Reviewed by Mike Wyrzykowski.
Core Image implementation of FEDropShadow. This works by extracting alpha via a
CIColorMatrix,
applying an offset (`imageByApplyingTransform:`), compositing with a color to
colorize the shadow,
and then compositing the original image with the shadow.
