I prefer create MR now to avoid biggest merge request.
It add minimalist implementation:
- First configuration of Waydroid
- Stop / Start Waydroid session
- Configure properties of Waydroid
- Display current ip of Waydroid

**Note for Reviewer**: In my local environment, i need to add manually the KAuth files otherwise polkit not recognize the implementation.

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)

Implementation of a popup button to rotate the screen while using gesture navigation.
The button is set to appear when the device rotates while auto rotation is off. Then the button will be visible for a short period of time before disappearing.
This is partially an emergency fix also for
https://invent.kde.org/plasma/plasma-mobile/-/issues/404, which was
potentially introduced by https://invent.kde.org/plasma/plasma-mobile/-/merge_requests/582
This MR extracts the screen brightness implementation from initialstart
to a QML plugin, and also ports the action drawer brightness slider
implementation to it. This avoids importing the powerdevil screen
brightness plugin on the lockscreen, which apparently has a race
condition that causes it to sometimes segfault.
This allows us in the future to use mobileshell without having the WindowUtil singleton loaded (which does a bunch of wayland calls that aren't necessary for most applications).
Move from a C++ library + QML plugin to a QML plugin only for simplicity, since the homescreen switching architecture will be done from Plasma, and so use of the shell library only needs to be from QML.
