Use HitTestQuery to transform locations in RWHInputEventRouter.

Currently in RenderWidgetHostInputEventRouter, we use
TransformPointToCoordSpaceForView [1] to transform locations, which uses
SurfaceHittest in normal chrome. We don't want to use SurfaceHittest in
normal chrome and can't use SurfaceHittest in OOP-D.

This CL changes to use HitTestQuery::TransformLocationForTarget instead.

Use HitTestQuery to transform locations in RenderWidgetHostViewBase.

1. Changed TransformPointToLocalCoordSpace to be non-virtual and use
HitTestQuery when we use Viz hit-test. If there are no viz::EventSource
specified, we match viz::EventSource::ALL (added) events. Added
TransformPointToLocalCoordSpaceLegacy (virtual) to do essentially what
TransformPointToLocalCoordSpace used to do on different platforms.

2. TransformPointToRootCoordSpaceF, TransformRootPointToViewCoordSpace and
TransformPointToCoordSpaceForView all use TransformPointToLocalCoordSpace
essentially, added necessary info to use the new version correctly.

3. Overridded GetRootFrameSinkId() in RenderWidgetHostViewChildFrame and
RenderWidgetHostViewGuest.
