Remove unnecessary saveLayer (#5420) 
saveLayer is slow so we should avoid it as much as possible. If
there are artifacts without saveLayer, then we should report that
to Skia for the fix instead of slowing the performance with
saveLayer.

This PQ makes average rasterizer time drop from 25ms to 18ms in
flutter_gallery transitions perf test on a Nexus 5X.

This partially fixes flutter/flutter#13736 .
We probably still need some work in the opacity layer to squize
all the performance improvements.

Flow

Flow is a simple compositor based on Skia that the Flutter engine uses to cache recoded paint commands and pixels generated from those recordings. Flow runs on the GPU thread and uploads information to the GPU.
