[torchlib] Improve/reimplement index_put

[justinchuby]

1. Handle None as inputs
2. Turn the function into trace_only
3. Fix failing CI tests

Ref:

• [ONNX] opset 11 aten::index_put generating invalid add ops with None args pytorch/pytorch#131349
• [ONNX] None as input to aten::index_put unsupported pytorch/pytorch#119363
