SkiaCompositingLayer: incorrect damage regions for overlap regions
https://bugs.webkit.org/show_bug.cgi?id=316050
Reviewed by Carlos Garcia Campos.
SkiaCompositingLayer::paintSelf() cleared m_layerDamage after painting.
However, paintSelf() can be called multiple times for overlap and non-overlap
regions.
Added SkiaCompositingLayer::recursiveCleanUpAfterPaint() to clean up
m_layerDamage after painting.
recursiveCleanUpAfterPaint() will be used for cleaning up local space surfaces
in the future.
