MSVC builds: Add support for introspection via NMake

This adds a set of NMake Makefiles that is used to build the introspection
files for librsvg, along with additions to the autotools file that uses the
common autotools module to generate another NMake Makefile module that would
contain the full command lines to g-ir-scanner and g-ir-compiler, which would
be called by these NMake Makefiles.
