Fix tab switcher animation offset in landsacpe mode

This CL will fix the tab switcher's shrink and expand animation offset
issue in landsacpe mode. The CompositorViewHolder's rect is different
from Hub layout's rect. So the same left offset of the animation initial
rect and final rect caused the animation's offset. So we need to use the
different left offset for initial rect and final rect.
