Summary
Add stream ID to GPU operators and support multiple streams in simulate_execution. There are two problems in the current main branch. First, the converter does not encode stream ID to GPU operators. Second, the simulate_execution method does not take stream IDs into account, resulting in the serialization of all GPU operators. As a result, for a specific trace, while the measured runtime is 4087.535ms, the simulated runtime with the simulated simulate_execution is 14802.3ms. This PR fixes the issue by encoding stream ID to GPU operators and supporting multi-stream in simulate_execution. Disabled simulate_execution by default because it takes too long now that the converter supports multiple streams.
Test Plan
1. Correlation 1
/tmp/rank_0
2. Correlation 2
Manually checked the simulated runtime.
