Only PaintLayerPaintingOverlayScrollbars is actually ever set
to a different value in different codepaths.
-PaintLayerHaveTransparency can just be replaced with
isTransparent() calls.
-PaintLayerPaintingCompositingScrollingPhase is unused.
-PaintLayerPaintingCompositingAllPhases is always set,
which means that the other three compositing ones are
also always set.
The third bullet more clearly falls out when you see that
the only caller of paintLayerContents is
paintLayerContentsAndReflection, which sets
PaintLayerPaintingCompositingAllPhases on the paint flags.
Get rid of paintLayerContentsAndReflection since we no
longer have reflections.
The rest of the changes are all just propagating the now
always false or true booleans in paintLayerContents.

It was added for compositing overflow:scroll, which we don't do.
This also means that only the RespectOverflowClip enum value is
used. And PaintingClipRectsIgnoringOverflowClip is unused.

Particularly, this deletes RenderLayerCompositor. After this,
there's just CompositingState left to remove.
This is all dead code, so there should be no change in behavior.

This caused us to lose our gn check certification. :(
Turns out gn check was just ignoring all the header
paths it didn't understand and so gn check passing
for sky wasn't meaning much. I tried to straighten
out some of the mess in this CL, but its going to take
several more rounds of massaging before gn check
passes again. On the bright side (almost) all of
our headers are absolute now. Turns out my script
(attached to the bug) didn't notice ../ includes
but I'll fix that in the next patch.
