Refactor code to use
metal::get_command_encoderandCommandEncoderAPIs, instead of theDevicemethods likeDevice::get_command_encoder/add_temporarythat take stream index.The motivation is that,
Deviceare global objects that shared by all threads, but we do not want to shareCommandEncoderbetween threads, which does not have any performance benefit and brings various race conditions. This refactoring would allow us to storeCommandEncoderin thread-local storages and detect thread-safety issues caused by using streams from different threads.
