[Profiler][Trivial] Move `PythonTracerBase` to `torch/csrc/profiler/orchestration` (#83895)
The ownership model between `RecordQueue` and `PythonTracer` is brittle; if a profiler is popped without proper shutdown it can dangle a reference in `PythonTracer` which will segfault when dereferenced. The next PR will address this; to start we simply move the code into `torch/csrc/profiler/orchestration` to limit the sloc delta when making actual changes.
