Reland "remove SkCanvas::kIsOpaque_SaveLayerFlag"
This reverts the revert 9ff8c8c073ba553dc8b22bb9aacc23949292f72f.
Original:
This is a performance-only hint that no one but fuzzers
is using. It's even explicitly filtered out in Android.
The fuzzers have noticed they can trick us into allocating
uninitialized memory and treating it as opaque, blending
uninitialized pixels, etc.
Since no one's using this, we can just kill the bit.
