Pull Request Overview

This PR implements the GetMethodTableSlot and GetMethodTableSlotEnum interfaces for the Contract Data Access Component (cDAC) system. These additions enable enumeration and retrieval of method table slots in the managed debugging environment.

• Implements GetMethodTableSlot to retrieve method entry points for specific slots in a method table
• Adds GetMethodTableSlotEnumerator with a new SOSMethodEnum class for iterating through all methods in a method table
• Extends the RuntimeTypeSystem contract with new APIs for slot management and method enumeration

The slot stuff looked fine to me, though I'm sure David has more expertise there than I do.

I think the follow up from that discussion about the API surface would be to define slots and IntroducedMethodDescs such that they return 0/empty enumeration for non-MethodTable based types rather than throwing an exception. You could do it in this PR or a separate one - whatever feels easier.
