Use Transactions for RefreshRateOverlay
RefreshRateOverlay currently calls directly in Layer to update
properties. This is ends up adding confusing code to RefreshRateOverlay
since it needs to notify SF to handle the updates. It also creates
addtional confusion since there are multiple entries to layer
properties.
Instead, use the SCC Transaction requests to accomplish the same
behavior. This simplifies the code and also allows SF to handle the
updates instead of RefreshRateOverlay invoking force updates.
Test: RefreshRateOverlay works with rotation, different refresh rates
Test: RefreshRateOverlayTest
