Add GPU acceleration for gamma component transfer filters
https://bugs.webkit.org/show_bug.cgi?id=296882
rdar://problem/157477030
Reviewed by Said Abou-Hallawa and Simon Fraser.
Support gamma-type feComponentTransfer in Core Image path. Previously,
only linear transfers were hardware-accelerated, forcing gamma
transforms to use slower software rendering.
