Dispatch refresh rate callbacks from DMS

AChoreographer will consume these callbacks in lieu of going through SF
for the callbacks. This is so that DMS can update its view of display
configs before apps receive the refresh rate callback so that apps can
get consistent information.

Test: ChoreographerNativeTest
Test: Manually verify that HWUI is receiving callbacks
