Shorten GPU names by dropping h. Fix intel Gen 12.7. (#786)

* Shorten GPU names by dropping h. Fix intel Gen 12.7.
   Plus some typos.
* Implement 'shorten' method for each name part
* fix typo, thanks unit tests
* bugfix: parameter got shifted
* Output shortened name in interactive CLI generator.
