Sandboxed apps that run without a window are detected by the new
background monitoring service, introduced by xdg-desktop-portal.
We have an opportunity to improve the predictability of the desktop
and ensure that application state in transparently reported to users
by showing these apps, and allowing them to closed.
Add a new background apps menu to the quick settings, that is always
added at the bottom of the popover, and has a slightly custom, flat
style applied to it.
Show background-running apps in this menu, and allow closing them
by first attempting to execute the 'quit' action through D-Bus, and
if that fails, sending SIGKILL to the process.
