Tristan Rice 3d541835d5 distributed debug handlers (#126601 )

This adds debug handlers as described in:
* https://gist.github.com/d4l3k/828b7be585c7615e85b2c448b308d925 (public copy)
* https://docs.google.com/document/d/1la68szcS6wUYElUUX-P6zXgkPA8lnfzpagMTPys3aQ8/edit (internal copy)

This is only adding the C++ pieces that will be used from the main process. The Python and torchrun pieces will be added in a follow up PR.

This adds 2 handlers out of the box:

* `/handler/ping` for testing purposes
* `/handler/dump_nccl_trace_pickle` as a POC integration with Flight Recorder

Test plan:

```
python test/distributed/elastic/test_control_plane.py
```
