Fixes for things that stopped working when we updated fontmake:
- restore glyph decomposition for VF
- restore glyph overlap removal for VF
- restore version metadata writing for VF
Improvements for VF
- fix "full name" name table entry to say "Inter" instead of "Inter Regular"
New and changed:
- "rename" command for renaming metadata like family and style, optionally
saving a separate file. Used to produce new "Inter V" family.
- The "build" command no longer performs "style name compactation" for
Google fonts. Instead, the new "rename" command is used.
