[Pytorch Profiler] Add debug_handles to KinetoEvent (#62228)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62228
This diff adds debug handles to events and provides a way to use
RECORD_FUNCTIONs that will pass debug_handles down to profiler, which
will record it in the events.
Why add debug_handles?
For pytorch mobile, with lite interpreter, we generate debug handles
that can be used for lazily symbolicate exception traces to model level
stack trace. Similar to the model level stack trace you get in
TorchScript models. The debug_handles also enable getting module
hierarchy for lite interpreter model, support for which was added to
KinetoProfiler in previous diffs.
Followup plan:
1. Enabled scope callbacks such that lite interpreter can use it to
profiler only top level ops.
2. Enable post processing callbacks that take KinetoEvents and populate
module hierarchy using debug handles.
This will let us use KinetoProfiler for lite interpter use cases on
mobile. Aim is to use RAII guard to similarly generate chrome trace for
mobile usecases as well, although only for top level ops.
