Use observed ptrs from CFGAS_GEFont back to its font mgrs.chromium/3106
CFGAS_GEFonts are ref counted, and its a good thing since they
are managed by at least three different font managers:
CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these
have a clear claim to ownership of the CFGAS_GEFont.
CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and
CXFA_PDFFontMgr, and they could each outlive the other. Thus the
font needs to watch for destruction of either of its managers, so
as to stop using it after its gone.
