CMake builds: Support introspection builds
This adds support for introspection builds on Windows that is enabled by the HB_HAVE_INTROSPECTION option, which will also enable HB_HAVE_GOBJECT (and so HB_HAVE_GLIB) as they are required for introspection. In order for this to work one must ensure that the Python installation listed in PYTHON_EXECUTABLE is the same Python release series that was used to build _giscanner.pyd (the Python module that is used by g-ir-scanner), with the same architecture. PKG_CONFIG_PATH and PATH must be set correctly if $(PREFIX)\bin and/or $(PREFIX)\lib\pkgconfig are not in the standard PATH and PKG_CONFIG_PATH, which is actually in-line with the *NIX builds.
