Add Lenovo ThinkPad X1 Yoga Gen 8

[bittner]

Convertible laptop equipped with e.g. 13th Gen Intel Core i7-1365U × 12, 32 GiB RAM, and 512 MiB or 1 TiB SSD HDD.

Description of changes

Adds a configuration, which is practically identical to the 7th-gen model.

@MayNiklas, would you mind to review?

Additional Context

1.) The model has a fingerprint reader integrated in the power button. I'm not sure whether this is already covered or I should to add the related configuration to this PR.

2.) My hardware-configuration.nix, which is derived from the one generated by the GUI installer, looks like this:

{ config, lib, modulesPath, ... }:
{
  imports = [
    (modulesPath + "/installer/scan/not-detected.nix")
  ];

  boot = {
    initrd.availableKernelModules = [ "xhci_pci" "thunderbolt" "nvme" "usb_storage" "sd_mod" ];
    initrd.kernelModules = [ ];
    kernelModules = [ "kvm-intel" ];
    extraModulePackages = [ ];
  };

  nixpkgs.hostPlatform = lib.mkDefault "x86_64-linux";
  hardware.cpu.intel.updateMicrocode = lib.mkDefault config.hardware.enableRedistributableFirmware;
  services.fwupd.enable = true;
}

Things done

• Tested the changes in your own NixOS Configuration
• Tested the changes end-to-end by using your fork of nixos-hardware and
  importing it via <nixos-hardware> or Flake input

Almost there :)

Please undraft when you are done.

I have a follow-up question: IIUC, the fingerprint reader and firmware updates are not enabled by default for Yoga models. Is there a good reason for this?

Would there be anything wrong with adding those two lines to the hardware configuration in this repository?

  services.fprintd.enable = lib.mkDefault true;
  services.fwupd.enable = lib.mkDefault true;
