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.

This Cl drops the FXSYS_ from mem methods which are the same on all

Moved all the flags to CFX_Font. Explicitly stated which ones are valued
according to the PDF spec to avoid their values being changed.
