Mike Klein 9ff8c8c073 Revert "remove SkCanvas::kIsOpaque_SaveLayerFlag" 
This reverts commit 9a7a2ee5ad.

Reason for revert: still need to update blink_headless in Google3

Original change's description:
> remove SkCanvas::kIsOpaque_SaveLayerFlag
> 
> 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.
>
