Raise TypeError when the argument to isinf and isfinite is not a tensor (#20817)
Summary:
Currently when the argument to isinf and isfinite is not tensor, a ValueError is raised. This, however, should be a TypeError, because the error is a type mismatch.
In the error message, "str(tensor)" is replaced by "repr(tensor)" because, when an error occurs, a printable representation of the object is likely more useful than the "informal" string version of the object.
