Only create
randomkey whenmx.random.stateis accessed, or whenrandomAPIs are used (which would create a key implicitly). This avoid initializing GPU device when runningimport mlx.core, which has been preventing us from doing any kind of error handling.Also the
randomkey is now declared as thread local, to remove race conditions when usingrandomAPIs in multi-threads.
