Make CPDF_Font a retainable type.

In turn, this makes CPDF_CountedObject<> unused, so remove it.

We have to explicitly break some cycles between fonts and forms,
so introduce a WillBeDestroyed() method.

This also introduces the requirement that callers of
FPDFText_LoadStandardFont() release the resource via a call
to FPDFFont_Close().
