generator: Rename 'generator_*' as '*'.

This is a simple renaming of the files/modules.

Note that in OCaml, module names are derived from filenames by
capitalizing the first letter.  Thus the old module names had the form
"Generator_api_versions".  The new modules names have the form
"Api_versions".
