Research direction

Review the discussion in #1916 to understand the requirements. Study the existing handler implementations in the repository (e.g., those in `ignite/handlers/`) to follow the same pattern. Refer to the PyTorch profiler documentation to know the API. Consider adding a handler that wraps the profiler's start and stop methods.
