Log Message:
-----------
CanvasRenderingContext2DBase should cache a generic ArrayPixelBuffer
https://bugs.webkit.org/show_bug.cgi?id=320773
rdar://183778041
Reviewed by Mike Wyrzykowski.
CanvasRenderingContext2DBase could only cache RGBA8 ImageData objects.
Using an ArrayPixelBuffer allows CanvasRenderingContext2DBase to cache
float16 ImageData as well, and any future pixel format.
Covered by existing tests.
