Remove NonCompositedContentHost -- Take 2
This patch was previously reverted for crbug.com/242626
The new version fixed the issue with deferred commit never get resumed,
and the issue with transparent WebView.
Safari uses a hybrid scrolling approach. For contents that require
compositing, they will create compositing layers and will use layer-based
scrolling. For non-composited contents, they will be painted to a native
window and will be scrolled with a OS-provided backing.
Chromium doesn't use this native window based scrolling. Instead,
NonCompositedContentHost was introduced to provide a replacement for
the OS-provided backing.
Now we no longer need to maintain compatibility with the native window
approach. This patch removes RenderLayerBacking::paintsIntoWindow().
Main frame contents will be painted onto its RenderView layer (which was
always created but only used as container for child layer), and
NonCompositedContentHost becomes redundant which gets removed too.
