Using the bus name to notify service startup to systemd has some
disadvantages. The main one being that systemd will consider a
gnome-shell restart (Alt+F2 r) a service failure and restart the shell,
cleaning up all its children (i.e. user launched applications). In the
future the shell should launch applications in their own transient unit
so that a service restart does not affect applications.
Another potential issue is that we must never load
gnome-shell-wayland.service and gnome-shell-x11.service at the same
time, as systemd does not like two services providing the same bus
name.

The existing units were never used as the corresponding support was
never merged into gnome-session.
This commits updates units to be usable with the newer gnome-session
unit definitions. Also added is appropriate failure/restart logic
including the ability to disable extensions. Note that extensions will
only be disabled if a failure happens in the first two minutes after
login.
