macOS: Native context menus

Popup context menus now use NSMenu. There are still has a few glitches with the navbar identity button, but most menus are working.

SDL required another little tweak to force it to update mouse button state after the synchronously handled  context menu goes away. Otherwise SDL's internal mouse button state shows that the right mouse button is held down.
