Subject: Move CXFA_PDFFontMgr to CFGAS_PDFFontMgr

XFA bits passed into the PDFFontMgr are just used to get the
CPDF_Document and the CFGAS_FontMgr. This CL changes the code to pass
those two things into the constructor. Then, the fxfa/cxfa_pdffontmgr.*
code has been moved to fgas/cfgas_pdffontmgr.* to show it doesn't depend
on any of the XFA classes.
