[Dynamo] Improve PT2 fbcode logging observability (#106932)
Summary:
https://docs.google.com/document/d/1D5K3_ELsda3tIUeSyNL_2yee-M3jVWbirqSQ5BDNvHQ/edit
This is the revamped version of D47908299.
For each frame, we will record a list of compilation metrics: e.g, backend_compile time, entire_frame_compile time, cache_size, co_filename, co_firstlineno, co_name, guards, graph input_count, graph node_count, graph op_count.
With the help of job info: mast_job_name, global_rank, we can satisfy the requirements from `Things I’ve used/wanted to use our logging to determine` in https://docs.google.com/document/d/1D5K3_ELsda3tIUeSyNL_2yee-M3jVWbirqSQ5BDNvHQ/edit (or add more metrics for this framework)
Test Plan:
```
buck2 test //caffe2/test:test_dynamo
