Pipe appTransition signal to taskbar to pause region sampling when it's ongoing 

For nav bar, RegionSamplingHelper calls LightTransitionsController#setIconsDark to apply color changes, which listens to mTransitionPending signal. For taskbar, due to the RegionSamplingHelper in Launcher and LightTransitionsController in SysUI, we need to pipe this signal (mTransitionPending) through.
