* gnome3: only maintain single GNOME 3 package set
GNOME 3 was split into 3.10 and 3.12 in #2694. Unfortunately, we barely have the resources
to update a single version of GNOME. Maintaining multiple versions just does not make sense.
Additionally, it makes viewing history using most Git tools bothersome.
This commit renames `pkgs/desktops/gnome-3/3.24` to `pkgs/desktops/gnome-3`, removes
the config variable for choosing packageset (`environment.gnome3.packageSet`), updates
the hint in maintainer script, and removes the `gnome3_24` derivation from `all-packages.nix`.
Closes: #29329
* maintainers/scripts/gnome: Use fixed GNOME 3 directory
Since we now allow only a single GNOME 3 package set, specifying
the working directory is not necessary.
This commit sets the directory to `pkgs/desktops/gnome-3`.
This is a squash commit of the joint work from:

- As noted on github, GDM needs different parameters for X.
- Making xserverArgs a true list instead of concat-string helps to
filter it and it feels more correct anyway.
- Tested: gdm+gnome, lightdm+gnome. There seems to be no logout option
in gnome, and gdm doesn't offer other sessions, but maybe these are normal.
This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
Or else users may see this unfriendly message:
error: cannot coerce null to a string, at .../nixos/modules/services/x11/display-managers/gdm.nix:107:49
