[torch] Add more functions to __init__.pyi.in for torch._C for Node and Value (#79654)
Summary:
https://github.com/pytorch/pytorch/pull/78757 recently added
a lot of functions to the type stub, but it missed a few of them.
This change will make sure every function is included, by making
sure this list is up-to-date with: `torch/csrc/jit/python/python_ir.cpp`.
This change only does this for Node and Value.
