[Simulator] Hardware-Accelerated Hardware Simulation

[chhzh123]

The current HLS simulation is too slow and only has sequential semantics for dataflow programs. We may want to build our own simulators in Allo that can simulate various dataflow programs in parallel.

Some reference simulators include:

• TAPA: https://github.com/rapidstream-org/rapidstream-tapa
• LightningSim: https://github.com/sharc-lab/LightningSim
• hls::task: https://docs.amd.com/r/en-US/ug1399-vitis-hls/HLS-Task-Library
