Handle RGBA_4444 scales in > max texture size images

Handle RGBA_4444 scales in > max texture size images

Currently, we have a hole in the GPU Image Decode Controller where a
greater-than-max-texture-size image, rendered in non-RGBA-8888 color,
and scaled down by more than 50%, will hit a guaranteed failure case in
Skia. This change adds a path which works around this failure case.
