[gjs/wip/require: 167/175] ns: Add gjs_import_gi_module



commit d6cf8196fb704bda76d5aca577b38624a6d86da0

    ns: Add gjs_import_gi_module
    
    This returns the bare module, and doesn't run overrides or anything like
    that yet... that will have to wait until after we get our new importer
    scheme working...
