[profiler][refactor] Refactor the usage of legacy profiler implementation (#61931) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/61931 This PR consolidates the profiling code around a new C++ implementation (profiler_kineto.h/cpp) and uses it unconditionally from torch.autograd.profiler/torch.profiler: 1. Always use profiler_kineto.h/cpp as the C++ implementation 2. Simplify profiler.py to remove unneeded parts depending on legacy impl 3. Move some of the legacy logic into profiler_legacy.py (to be fully deleted later) Test Plan: USE_KINETO=1 USE_CUDA=1 USE_MKLDNN=1 BLAS=MKL BUILD_BINARY=1 python setup.py develop install --cmake python test/test_profiler.py -v USE_KINETO=0 USE_CUDA=1 USE_MKLDNN=1 BLAS=MKL BUILD_BINARY=1 python setup.py develop install --cmake python test/test_profiler.py -v Imported from OSS Reviewed By: gdankel Differential Revision: D29801599 fbshipit-source-id: 9794d29f2af38dddbcd90dbce4481fc8575fa29e
