Draft: tools/custom-quick-settings: Init shell object
More complex plugins like mobile-settings and night-light want PhoshShell
so we need to set it up.
The downside is that you have to run through a Wayland compositor like:
WLR_BACKENDS=wayland phoc -E '_build/tools/run_tool _build/tools/custom-quick-settings'
