New GLProfile.ShutdownType: SHARED_ONLY / COMPLETE - Enhance/Fix Lifecycle Management

- Leave Platform, .. TempJarCache untouched.

- GLDrawableFactoryImpl*: Leave DynamicLibraryBundle(lib-binding) untouched,
  for NativeLibrary, JNILibLoaderBase (JNI libs), .. consistency.

- SHARED_ONLY: shutdown shared GLDrawableFactoryImpl* resources and NativeWindowFactory

- COMPLETE: additionally shutdown GLContext*
            Clear all cached GL/GLX proc-address and device/context mappings.

- Use new "GLProfile.shutdown(GLProfile.ShutdownType.SHARED_ONLY)" in Applets

- X11GLXDrawableFactory Shutdown: Uncomment close/destroy of shared resources.

- JAWTWindow.destroy(): Close the delegated device.
  In case it's X11 this closes the exclusive opened X11 Display.
