Fixing ONNX export of logical ops to have correct output datatype (#15185)
Summary:
Currently PyTorch ONNX exporter exports the logical ops (`lt`, `gt`, `le`, `ge`, `eq`) with output type in corresponding ONNX ops as type `tensor(uint8)`. But ONNX spec allows for only `tensor(bool)`, which is why models that have these ops fail to load properly.
This issue is captured in https://github.com/pytorch/pytorch/issues/11339. Part of this issue, relating to the allowed input types, has been fixed in ONNX spec by houseroad. This PR fixes the other part pertaining to output type.
