Update Talos template, platforms, add custom args

* Cleans up the Talos.ipxe menu and add custom_kernel_params to
  template.

* Add a new argument `custom_kernel_params` that can be used to modify
  the parameters passed to the Talos kernel specifically (and updates
  kernel parameters to latest)

* Add a number of new supported arguments for the `talos.platform`
  variable (and fix some platform names)
