What is the problem that this feature solves?

IsInf and IsNaN support a limited set of data types. This makes the converter's job harder when for example we need IsInf on FP16 or INT.

Alternatives considered

Manually add cast nodes in graphs.

Describe the feature

For broad compatibility, it would be great to make IsInf and IsNaN support all numeric data types.

For any floating point numbers FP8, FP16 etc., Inf and NaN should be well defined. For integers, they can always return False.
