generate_wrap_init.pl.in: Disable warning C4273

... for Visual Studio builds, as GLib 2.75.x and later applied
__declspec(dllimport) via macros to DLL builds of the GLib libraries,
meaning that when we put the GQuark and GType function prototypes into
wrap_init.cc warning C4273 will be raised as the prototypes in
wrap_init.cc does not have any dllimport decorations (and would not have
otherwise mattered).

This allows builds with '-Dwarnings=fatal' to proceed with Visual Studio
builds.
