This should make it possible to launch wayland sessions using nvidia hardware.

Does this support gdm? I wasn't able to do: services.xserver.displayManager.gdm.enable = true;
services.xserver.displayManager.gdm.wayland = true;
services.xserver.desktopManager.gnome3.enable = true;

#70295 should hopefully complete this. |

Motivation for this change
Make it possible to run a gnome shell wayland session using nvidia drivers.
This is supported on both fedora and arch.
Things done
Checked that
mutterruns (mutter --wayland --nested), but I don't have any nvidia hardware so can't be sure that the intended functionality actually works.I opted to package https://github.com/NVIDIA/eglexternalplatform inline.
