Fix wallpaper flicker issue while transiting from home to aod.
There is a race condition between window visibility and wallpaper
transition, so wallpaper window might become visible before background
thread has done its rendering work and a flicker happens.
This solution just lets main thread wait for background thread to
synchronize window visibility and wallpaper transition.
Bug: 136643341
Test: atest SystemUITests
Test: Screen off Launcher/APP -> AOD : No extra transition by design,
The duration between press Power Key and AOD show should be same.
