[chromium] Remove the WebCompositorSupport methods for changing settings, plumb everything through WebLayerTreeSettings
https://bugs.webkit.org/show_bug.cgi?id=101968
Reviewed by James Robinson.
Source/Platform:
Move the outlier settings from WebCompositorSupport to WebLayerTreeView.
PerTilePainting and AcceleratedAnimations are simply moved over. The
PartialSwap and PageScalePinchZoomInCompositor settings, however, are
not used by DRT, so we remove them.
This change will temporarily break the --per-tile-painting and
--accelerated-animations command line flags for chromium DRT until
a chromium side patch hooks up the WebLayerTreeSettings again, but
we have no bots running with these flags.
PinchZoom will be unaffected by this, as DRT never turned it on, and by
passing the WebLayerTreeSetting, chromium will not use it from here yet,
either.
PartialSwap will be also unaffected, as there was no place in WebKit
that would enable it currently.

This adds perTilePainting and acceleratedAniamtions to the WebSettings
classes, so that DRT can turn these on via WebLayerTreeSettings.
