2828ce53 - Added jit log stream changing function and some refactor (#65768)

Added jit log stream changing function and some refactor (#65768) Summary: Description: - Have only added `stdout` and `stderr` as possible options from python API for now. We can do file path passing later maybe. - Put the class `JitLoggingConfig` in the cpp file as none of its methods were being used outside of this file. Python API: `torch._C._jit_set_logging_stream('stdout|stderr')` C++ API: `::torch::jit::set_jit_logging_output_stream(ostream);` Testing: - Tested python API locally. - Unit test for the C++ API is written Fixes https://github.com/pytorch/pytorch/issues/54182 Pull Request resolved: https://github.com/pytorch/pytorch/pull/65768 Reviewed By: mrshenli Differential Revision: D31291739 Pulled By: ZolotukhinM fbshipit-source-id: eee72edc20488efad78a01c5b0ed8a132886a08d
