Remove IFGAS_FontMgr and clean up (the renamed) CFGAS_FontMgr a little.

IFGAS_FontMgr is an interface only for a class only defined on Windows,
plus a class only defined for non-Windows. I'm removing the interface,
renaming the class to have the same name in both cases, and cleaning up
a bit of unused methods.
