Add SF side tunnel mode listener

This CL adds a TunnelModeStateReporter, which monitors if there are
any layers with a sideband stream in SurfaceFlinger. If any of the
layers have a sideband stream, it informs all the registered listeners
that tunnel mode is enabled. When no layers have a sideband stream, it
notifies the listeners that tunnel mode is disabled.
