[libkineto] Refactor 4/n: Simplify activity logger step 2/3 (#68329)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68329
Pull Request resolved: https://github.com/pytorch/kineto/pull/466
1. Generalize ChromeTraceLogger::handleGenericActivity to enable it to handle Cuda runtime activities as well as the Roctracer generic activities.
This primarily involves enabling generic support for CPU -> GPU flows.
2. In the event of out-of-order GPU activities (an issue with Cuda11.0, likely fixed in later versions), no longer remove them but print warnings. Another diff will add these warnings to the metadata section.
