SF: Add RefreshRateSelector to LayerInfo via LayerProps

Add RefreshRateSelector to LayerInfo via LayerProps to simplify method
interfaces in LayerInfo and LayerHistory by removing the selector from
the argument.

To match LayerInfo to RefreshRateSelector, add LayerFilter to
RefreshRateSelector, which is already per-display. The filter is fed in
from DisplayDevice when its filter is set.

Add Scheduler::getRefreshRateSelectorForLayerStack() to obtain the
proper selector for a given layer snapshot via its stack.

Internalize isActiveLayer() helper from LayerHistory in LayerInfo.
