New selection strategy "DoNotPropagate"

Add new FrameRateSelectionStrategy::DoNotPropagate.
The default behavior ("Self") is to propagate parent vote to children
that has no votes, but if a layer has "DoNotPropagate", it will not
propagate its vote to children. This can be used on ViewRootImpl to
avoid incorrectly propagating frame rate category "NoPreference" to
content SurfaceControls.
