Description
Implement a workaround for a potential bug in the ROCm framework that causes deadlocks on StableDiffusion models when executed with profiling enabled.
Motivation and Context
ORT deadlocks when executing the StableDiffusion model on AMD GPUs with ROCm profiling enabled. I suspect that this is most likely a bug in the ROCm framework, which is triggered by enqueueing a callback on the device stream, and then immediately synchronizing on the stream.
In this particular case, there isn't really a necessity to do this: we can swap the order by first synchronizing on the stream and then releasing the buffers synchronously, once we know that the device stream has completed execution.
