Merge pull request #231293 from K900/libinput-default

- [services.xserver.videoDrivers](options.html#opt-services.xserver.videoDrivers) now defaults to the `modesetting` driver over device-specific ones. The `radeon`, `amdgpu` and `nouveau` drivers are still available, but effectively unmaintained and not recommended for use.

- [services.xserver.libinput.enable](options.html#opt-services.xserver.libinput.enable) is now set by default, enabling the more actively maintained and consistently behaved input device driver.

- To enable the HTTP3 (QUIC) protocol for a nginx virtual host, set the `quic` attribute on it to true, e.g. `services.nginx.virtualHosts.<name>.quic = true;`.

- In `services.fail2ban`, `bantime-increment.<name>` options now default to `null` (except `bantime-increment.enable`) and are used to set the corresponding option in `jail.local` only if not `null`. Also, enforce that `bantime-increment.formula` and `bantime-increment.multipliers` are not both specified.
