    Windows: Fix DllMain() for running on SpiderMonkey 38
    
    It appears that we need to call JS_ShutDown() during DLL_THREAD_DETACH
    right after we call gjs_destroy_runtime_for_current_thread(), otherwise
    when for example gjs-console finishes running the script, it will not exit
    as the SpiderMonkey JS engine did not ShutDown.  This appears to be in
    line with what is done on non-Windows.
    
    We still need to call JS_Init() during DLL_PROCESS_ATTACH (which is
    simplified a bit, as we can just set gjs_is_inited based on the results
    of JS_Init() and so assert later on that JS_Init() did indeed succeed).
