Respect bar transition delay of remote animation

So the light bar animation can fit at proper timing with app launch
animation. It also avoids CPU contention such as the bar animation
won't overlap with app creation at the initial ~280ms.

Test: adb shell setprop persist.wm.debug.shell_transit 1; reboot
      Set wallpaper to pure white (status bar text color is black).
      Launch Clock (black background) from launcher. The status
      bar text color will change to white until the animation is
      close to the end.
