Resolve CompoundButton's foreground drawable for layout direction change

This CL adds a step to resolve CompoundButton's foreground drawable when
layout direction has been changed. Prior this CL, only background drawable
of the button resolves its layout direciton in respond to system wide
layout direction change. This CL makes the foreground and background
drawables consistent in layout direciton.
