Subject: [PATCH 1/2] classic: Add X-GNOME-SessionRegisters
GDM has supported sessions registering with it for a few years now so
it can know when to shut down the greeter. Having the GNOME Classic
session declare that it will register itself allows GDM to avoid
executing a fallback codepath.
This has been supported with the regular GNOME session for a while,
and this session was likely forgotten about when it was added there.

Subject: [PATCH 2/2] classic: Install the session for Wayland and ship
override sessions
The regular GNOME session ships with three options:
* GNOME
* GNOME on Wayland (available when GDM starts in X11)
* GNOME on Xorg (available when GDM starts in Wayland)
The main GNOME session is set up so it works to match how GDM starts,
so GNOME is on Wayland if GDM is (or GNOME is on X11 if GDM is).
For GNOME Classic, we are missing this setup, so port this behavior
over from the GNOME session setup.
