Remove the non prefix validation options from Options.

The other generation options never were in the Options structure and
ImportWriter was the only thing that needed some the non validation options and
it already required directly passing the options. So refine Options to just be
validation options and bundle all the File related generation options into
a new FileGenerator specific GenerationOptions.
