Subject: [PATCH] Add rtl activity animations

Add support for animating in the other direction which is more natural for devices using right to left layout instead of left to right. Make is consistent with what is done for task transitions as well.

Bug: 221235072

Test: Toggle RTL switch in developer options and make sure transition looks good
