[WIN32K]

- Calculate font name hash in GreHfontCreate
- Partly implement LFONT_ppfe, which finds a matching PFE for an LFONT
- Implement PFE_ulPenalty, that calculates a penalty value from a PFE based on a LOGFONT
- Implement HASHBUCKET_ppfeFindBestMatch, that finds the best matching PFE from within a HASHBUCKET
- Implement PFT_ppfeFindBestMatch, that finds the best matching PFE from a PFT
- Rename PFT_pffFindFont to PFT_pffFindFontByFile
- Use bitfields instead of BOOLs in RFONT structure
- Add a name hash value to the LFONT structure
- Add a FONTSUBSTITUTE structure that will be used for font substitutions
