Add debug logger showing the glyph name for which gvar is built

Browse Source 
When building gvar, some situations cause fontmake/varLib to fail, for example if a component has a coordinate that's >32k or <-32k. This adds a debug line that prints each glyph name for which gvar is built, so it’s easier to pinpoint where the faulty glyph is.
