This PR fixes https://github.com/apache/tvm/issues/19533: - Sanitize floating tensor min/max: replace NaN with +inf/-inf before topi max/min so bounds match ONNX "unbounded" semantics where NaN bounds default to no constraint. - After clamping, preserve NaNs from the input tensor on floating dtypes. - Extend check_correctness with equal_nan for float outputs containing NaN. - Add parametrized Clip opset-13 tests for NaN min/max tensor bounds.
