Expose cudaStreamCaptureMode in CUDA Graphs, use local setting in inductor (#107407)
> capture_error_mode (str, optional): specifies the cudaStreamCaptureMode for the graph capture stream.
Can be "global", "thread_local" or "relaxed". During cuda graph capture, some actions, such as cudaMalloc,
may be unsafe. "global" will error on actions in other threads, "thread_local" will only error for
actions in the current thread, and "relaxed" will not error on these actions.
Inductor codegen is single-threaded, so it should be safe to enable "thread_local" for inductor's cuda graph capturing. We have seen errors when inductor cudagraphs has been used concurrently with data preprocessing in other threads.
