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.
