Devin Lin acde5b389d lockscreen: Dynamically load status bar and action drawer as needed for performance
Currently the lockscreen takes 5 seconds to load for me on the OnePlus 6. This MR moves the quicksettings and status bar to only load once the initial lockscreen has loaded (to avoid blocking it). This brings it down the initial load to 1 second for me.
