Associate RenderNodes created for hw bitmap w/ views

In transition animations, in order to capture the content of a view
or a drawable in a hw bitmap, a RenderNode needs to be created. The
RenderNode was previously setup with no owning view. As a result,
in cases where RenderNode animations are triggered by the draw calls
in displaylist recording, these animations would fail for lack of a
view to animate on.

This CL ensures that when RenderNodes are created for the purpose of
populating content in a hw bitmap in transitions, there's always a
view associated with each RenderNode.

BUG: 65160121
Test: Force to repro crash by changing press state during hw bitmap
creation, which triggers a ripple animation that led to the
otherwise timing dependent and hard to repro crash.
