Remove CFX_PrivateData from CPDF_ModuleMgr

Its only used to store one object, so replace it with a unique_ptr
to a class with a virtual dtor.  Rename the prototypical class with
virtual dtor from CFX_DestructObject to CFX_Deletable. Rename the
fx_basic_module.cpp to cfx_modulemgr.cpp to match the one class
in it.
