157a3d2a - [Profiler] Move legacy profiler out of `torch/csrc/autograd` (#85512)

[Profiler] Move legacy profiler out of `torch/csrc/autograd` (#85512) The legacy profiler is an eyesore in the autograd folder. At this point the implementation is almost completely decoupled from the rest of profiler, and it is in maintaince mode pending deprecation. As a result, I'm moving it to `torch/csrc/profiler/standalone`. Unfortuantely BC requires that the symbols remain in `torch::autograd::profiler`, so I've put some basic forwarding logic in `torch/csrc/autograd/profiler.h`. One strange bit is that `profiler_legacy.h` forward declares `torch::autograd::Node`, but doesn't seem to do anything with it. I think we can delete it, but I want to test to make sure. (Note: this should not land until https://github.com/pytorch/torchrec/pull/595 is landed.)
