Félix Baylac Jacqué 09bb6a055d modules/power_profiles_daemon: safely call dbus asynchronously ...

2 changes to address the review feedback:

1. Aleksei pointed out in this
   comment (https://github.com/Alexays/Waybar/pull/2971#issuecomment-1972364896)
   that there's no way to tell if a proxy is alive other than trying to
   call a method on it. We perform a little dance to check whether or
   not power-profiles-daemon is available on the system by calling
   properties.GetAll. If something responds, we assume
   power-profiles-daemon is installed, it's then safe to draw the
   widget and attach the callback to the active profile.
2. We replaced all the synchronous DBus operations by their async
   counterparts.
