Log Message:
-----------
Use the Copy CompositeOperator when copying canvas into its layer.
https://bugs.webkit.org/show_bug.cgi?id=253614
Reviewed by Simon Fraser.
When the canvas buffer is the only draw into the layer, we should be able to
just directly copy the pixels instead of blending.
This also means we can skip clearing the back buffer.
