Amend GlyphMapForStandardFonts to fix issue 4276

This PR adds more entries in `GlyphMapForStandardFonts`, in order to fix #4276.
I've checked a number of standard fonts (with the help of TTX) and they all seem to agree on the CID <-> GID mapping.

I expect one text failure, in bug921760.pdf, since the hyphen is currently incorrectly mapped (causing it to be replaced with a rectangle instead). This change also removes https://github.com/mozilla/pdf.js/issues/3191#issuecomment-34492466.
