Change screen rotation animation

Screenshot no longer scales to fit
new layout dimensions.
Added color layer underneath to not
have "empty" black spots
Add separate custom fade in/out animation
durations and interpolators.

Fixes: 142332867, 143780390
Test: Tested rotation in from all 4
orientations to the other 3. Tested full
screen app rotation as that has separate
code flow. Currently only code flow using
custom animations is user switching, tested
that as well. (Note that animation doesn't
actually rotate the screen but only does
a fade animation.)
