nvidia-x11.vulkan_beta: init at 450.56.11 (#97882)

- This is fetched from a different URL, so allow passing that explicitly.

- There also isn't an nvidia-persistenced or nvidia-settings release for
  this version, so use 450.57 instead. Also implement passing
  persistenced and settings version explicitly.
