nixos/x11: refactor XKB options into a single attrset

[Motivation](https://github.com/NixOS/nixpkgs/issues/257817#issuecomment-1741705042):

- Having all the XKB options in the same attribute set clarifies their
  relation better than using a common option name prefix ("xkb").
- `services.xserver.layout` is an XKB option, but this is not obvious
  from its name. Putting it with the other XKB options clarifies this.
