Make TransformTree::CombineTransformsBetween run faster
TransformTree::CombineTransformsBetween is modified to compute the
combined transform between source and destination directly (without
walking the path) when the destination and all its ancestors are
flat. A unit test is added to validate the patch.
BUG=475636
TEST=passes all the unit tests along with the one added to validate the
patch. Telemetry test on poster circle page shows improvement in
performance. The draw_properties.tough_compositor:CDP_reduction percentage
improved from -287.82% to -149.36%.
