Some fixes to the fallback font code.
This CL applies several fixes to the fallback font code.
- PDFium uses -1 to indicate that no glyph index was found, but freetype uses
0. In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which
means we should try to find the glyph from a fallback font.
- Improve the fallback glyph calculation by going from original font charcode
to unicode to fallback font charcode.
- Consider the m_ExtGID on Mac when deciding the fallback.
