GuidedStep: sync selectorView translationY to focused view
Current implementation assumes the focused view stays at fixed Y location.
This is no longer true for expanded actions.
This CL added support to sync selectorView Y position to focused
view Y position. And due to the conflicts of both IME and scroll changes
selector Y position, added common parent for change Y position for IME.
Simplified selectorView animation implementation.
Fixed bug that FadeAndShortSlide resets transitionY to 0.
Fixed a mismatch of transitionName for guidedactions_root2.
Remove unnecessary transition excludes since the views are already part
of shared element transition.
Tested by changing alignment rule of VerticalGridView.
