Unify XP Pen tablet drivers

[sochotnicky]

Description of changes

This implements changes proposed in #213263 to unify drivers for XP Pen devices in one application.

XP Pen app has hardcoded /usr/lib/pentablet path in the binary that can't be overriden and so we need to create FHS structure for it.

Known issues:

• Runs but probably does not work on Wayland
• Breaks on multi-user systems because it doesn't cleanup after exit (it leaves lock file around so different users can't run the app).

TODO:

• Add hardware module with udev rules that will provide access to the devices for ordinary users. Basically: SUBSYSTEM=="usb", ACTION=="add", ATTRS{idVendor}=="28bd", MODE="0660", TAG+="uaccess"

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 24.05 Release Notes (or backporting 23.05 and 23.11 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

Hi @sochotnicky, are you still interested in working on this?

In #351647 I added a generic/unified derivation for all XP-Pen drivers and made major versions available as xppen_3 and xppen_4. It also has a NixOS module that adds the xppen package as a udev package, which should take care of your TODO.

However the removal of g430 and deco-01-v2 drivers is only done in this PR, after a rebase you could add an alias that points to the unified packages.

I no longer have access to the device so I can't really finish this off and test it.

Since it's been a good long while and I don't have this device anymore - I'll close but if anyone wants to pick it up feel free to reuse if it makes sense
