In the 'Ice/optional' tests, we have this operation: bool supportsCsharpSerializable();
C# used to call this in the cross-tests to determine whether it should run tests involving serialization.
But... C# serialization support was removed 6 months ago in #1594
So, this function is never called anymore; so this PR removes it.
