Rename hiddenapi config files

Rename files to reflect new API list naming convention:
  light-greylist => greylist
  max-sdk-p-blacklist => greylist-max-p

This also removes unused files (private-dex.txt, public-dex.txt,
removed-dex.txt) and merges vendor.txt into greylist.txt.

The CL also starts using greylist-max-p.txt (which is currently empty).
