This also updates the WebRenderScrollDataWrapper function as it is meant
to be semantically equivalent to the LayerMetricsWrapper one, which
allows removal of a flag propagation.

This propagates the animation id for a scroll thumb's stacking context over to
the APZ code, and stores it in the HitTestingTreeNode.

This is preparation for future changes that will add fields to ScrollThumbData
that will be accessed via HitTestingTreeNode.
To accomplish this, this patch also exposes the entire ScrollThumbData via
LayerMetricsWrapper and WebRenderScrollDataWrapper.

This further abstracts away the direct dependence on particular layer
types. This is needed in particular for the APZCTreeManager call site
since it will need to operate on non-layer-tree data which is hard if it
relies specifically on RefLayer.

Fix thumb position determination in these places:
- nsSliderFrame::StartAPZDrag() -- Constrain sliderTrack using
GetXULClientRect() to match dimensions used in
SetCurrentThumbPosition() and DoXULLayout(). This is what caused
the scaling/offset mismatch.
- nsSliderFrame::StartAPZDrag() -- Adjust nonsensical calculation of
cssSliderTrack. Should be sliderFrame + scrollbarFramePosition -
compositionBoundsPosition, to get coordinates relative to the same
region as that of APZ event coordinates.
- AsyncDragMetrics -- Make mScrollTrack and mScrollbarDragOffset float
instead of int coordinates.
- AsyncPanZoomController::HandleDragEvent() -- Use
GetAxisLength(scrollTrack) instead of GetAxisEnd(scrollTrack) in
calculation of scrollMax.
- AsyncPanZoomController::HandleDragEvent() -- Only change position on
MOUSE_MOVE.
Additional refactors:
- Rename HitTestingTreeNode::GetScrollSize() to GetScrollThumbLength(),
along with related functions/variables.
- Rename AsyncPanZoomController::GetAxisSize() to GetAxisLength().
- Rename cf to scrollFrame in nsSliderFrame::StartAPZDrag().

Change interface of getter/setter for mClipRect,
also necessary modification for codes that use these resources.
* * *
Bundle mUseClipRect and mClipRect as Maybe<ParentLayerIntRect> mClipRect
When the event-regions are provided by layout, use them to populate the APZ-side
hit testing regions. The existing code is still used when event-regions are not
provided by layout.
