Karl Ostmo 8f0603b128 C++ changes toward libtorch and libcaffe2 unification (#19554)
Summary:
* adds TORCH_API and AT_CUDA_API in places
* refactor code generation Python logic to separate
  caffe2/torch outputs
* fix hip and asan
* remove profiler_cuda from hip
* fix gcc warnings for enums
* Fix PythonOp::Kind

* Note: for constant nodes (prim::Const) we generate a separate op in the net,
* which might or might not be what we want. The idea here is that eventually
* both formats will converge to PyTorch IR, so for now we try to keep as close
* to it as possible. For short-term applications we might add a separate pass
* that would fold such const-nodes into their users.
* \p If Prefix is specified, the prefix will be removed from operator name when
* converting from IR to NetDef.
*
* TODO: We might need to do a better job at preserving names of the variables,
* especially external_inputs/external_outputs.
