[NTGDI][FREETYPE] lfEscapement for TextOut (#4920)

Rotation and shearing transformation of font/text is now available. Retrial of PR #1207.
- Rename ftGdiGetTextWidth as IntGetTextDisposition and add a Y parameter.
- Apply lfEscapement values (by multiplying matrices).
- Add IntEngFillPolygon and IntEngFillBox helper functions.
