Justin Chu 0d76299ff7 [ONNX] Clean up module imports (#77423)
Cleaning up onnx module imports to prepare for updating `__init__`.

- Simplify importing the `_C` and `_C._onnx` name spaces
- Remove alias of the symbolic_helper module in imports
- Remove any module level function imports. Import modules instead
    - Alias `symbilic_opsetx` as `opsetx`
- Fix some docstrings

Requires:
- https://github.com/pytorch/pytorch/pull/77448
