[nvFuser] Improving bitwise ops support (#77158)
- Some renaming to better match PyTorch API:
- `lshift` -> `bitwise_left_shift`
- `rshift` -> `bitwise_right_shift`
- `andOp` -> `bitwise_and`
- `orOp` -> `bitwise_or`
- `xorOp` -> `bitwise_xor`
- `notOp` -> `bitwise_not`
- Fix type inferences and type checking of these ops
- Add `bitwise_*` to parser and python frontend
- Improve test coverage
