VIZ: Enable some Surface Sync support on Android

Generate viz::LocalSurfaceIds in RenderWidgetHostViewAndroid, causing
Android RenderWidgets to be sent surface IDs and unblock raster /
frame submission. We only generate new Surface IDs for basic resize
cases at the moment, and will need additional handling for other cases
(omnibox, selection handles, autoresize?).

Also works around compositor metadata change issues with by temporarily
ignoring these msismatches. This will be fixed with future renderer
local surface ID generation work.

Surface synchronization: Check surface invariants on Android

We would like to start a Finch trial for surface sync on Android soon.
This CL re-enables Android-specific surface invariants violations checks
on Android by removing code in RenderWidgetHostImpl that bypasses those
checks. This CL also ensures that when the background transparency
changes a new LocalSurfaceId is allocated as this matches the behavior
pre-surface-sync.

There isn't a whole lot of android specific work left to do here so I'm marking this as FIXED.
