…tate (dotnet#110449) Some methods have a nil token - for example, special runtime methods like array functions. When we tried to look up their IL version state, we were throwing an exception. Methods like this will have no versioning state, so check for a nil token and skip the lookup.

Found this while trying to finish out
RuntimeTypeSystem_1.GetMethodClassificationDataTypefor #109426 when doing a!dumpmdfor an array function. I also uncovered another issue where we aren't getting the native code slot correctly for some methods, but haven't fixed that yet - will be a separate change.Contributes to #99302, #109426
