Fix icon and DWB toast focus transition

- icon and DWB toast now transition in with animation when swipe up from apps to Overview
- Refacotred focusTransition into MultiProperty, with separate control from fullScreenProgress and scaleAndDim, and get rid of "invert" parameter and iconScaleAnimStartProgress variable which is very confusing
- Added a SCALE_AND_DIM_OUT property for use with PendingAnmation during dismiss, as PendingAnimation does not support per animator interpolator
- Use height from resource in DWB toast when calcualting translation, so translation can be properly set before view is measured
- Always set bannerOffsetPercentage regardless if banner is added
