The system tray has not been useful on mobile and isn't particularly
interactable due to its small size. Remove the system tray from the
status bar, if we need its functionality it would be more appropriate to
create a larger "tray UI" in the quicksettings area
Overlay the shell's status panel and quicksettings panel over the lockscreen, instead of rendering a second copy in the lockscreen theme. This will allow us to improve the lockscreen loading speed.
Key changes:
- Overlay quicksettings window and the status bar over the lockscreen when it is shown
- Refactor the top panel's showing logic to be cleaner (as it supports various overlay modes over fullscreen apps already)
- Implement lockscreen support to the status bar and quicksettings panel in the to panel
- Forward quicksettings panel requests for "unlock" over DBus to the lockscreen
- Add "raiselockscreen" QML plugin to easily request a window to be raised over the lockscreen
Notes:
- Now that we are sharing the quicksettings panel from the shell, notifications that are already there will be shown on the lockscreen (compared to right now, where only new notifications would be shown)

BUG: 484054
This is a potential fix for the input to stop working. There was unused code for passwordless login that could cause the "waitingForAuth" variable to never be set to false after user input.
