Split the font_spec.js unit-tests into cff_parser_spec.js and type1_parser_spec.js 

Re: issue 7261.

Given the we have `gulp fonttest`, which tests the `fonts.js` functionality at a higher level, and that we have *a lot* of font specific reference tests, I'm not convinced that we *also* need unit-tests for it.
