Remove core/include/fpdfdoc/fpdf_vt.h

This CL removes the core/include/fpdfdoc/fpdf_vt.h file. The IPDF_VariableText
class was removed in favour of the only concrete class of CPD_VariableText.

CPVT_Provider was moved to CPDF_VariableText::Provider and
CPDF_VariableText_Iterator was moved to CPDF_VariableText::Iterator.

The IFX_Edit_FontMap interface was merged into the IPVT_FontMap interface so
there is only one.

Other classes were split out as needed in order to keep things compiling.
