vcl: Rename class ImplFTSFontData to FreetypeFontFace

ImplFTSFontData derives from PhysicalFontFace, and implements the
mechanisms specified therein. It's not actually a "data" class, but
also implements a factory function that creates a
LogicalFontInstance object via Freetype. I believe the "S" in "FTS"
stands for "Server", which is a misnomer as Freetype is a font
renderer, not a font server.
