d9024ea2 - Setup torch/csrc/functorch/*; move CompileCache.{h, cpp} there (#85263)

Setup torch/csrc/functorch/*; move CompileCache.{h, cpp} there (#85263) The plan for functorch C++ is: - all C++-only code goes into aten/functorch. - any C++ code with a python dependency goes into torch/csrc/functorch. This will include the functorch Python bindings as well as all of torchdim. Alternative: - we could split it so that code goes into torch/csrc/functorch/nopython and torch/csrc/functorch/python instead of putting anything into ATen. This just feels like a matter of cosmetics. This PR also does two more things: - fix a windows lint error regarding PyLong_asLong - clang-format the code (because the linter got triggered) Test Plan: - run tests - check internal build Fixes #ISSUE_NUMBER Pull Request resolved: https://github.com/pytorch/pytorch/pull/85263 Approved by: https://github.com/ezyang
