Enhancement: Add nsys and pytorch profiler debug trace support

[polarG]

To improve benchmark debugging, the following debug methods were added:

pytorch profiler in model benchmark

• SB_ENABLE_PYTORCH_PROFILER: switch to enable/disable
• SB_TORCH_PROFILER_TRACE_DIR: log path
  These 2 runtime variables need to be configured in SB config file.

nsys in SB runner

• SB_ENABLE_NSYS: switch to enable/disable
• SB_NSYS_TRACE_DIR: log path
  These 2 runtime variables need to be configured in runner's ENV
