Add cDAC API GetCCWData

[Copilot]

• Adds cDAC SOS API GetCCWData
• Adds following contract APIs:

// Returns the GC object handle from the given ComCallWrapper.
public TargetPointer GetObjectHandle(TargetPointer ccw);
// Returns the data stored in the SimpleComCallWrapper associated with the given ComCallWrapper.
public SimpleComCallWrapperData GetSimpleComCallWrapperData(TargetPointer ccw);
// Navigates to the start ComCallWrapper in a linked chain.
// If ccw is already the start wrapper (or the only wrapper), returns ccw unchanged.
public TargetPointer GetStartWrapper(TargetPointer ccw);

GetSimpleComCallWrapperData supersedes GetRefCount and IsHandleWeak

The code is fine but the PR description appears misleading, this PR is doing a lot more than just a contract API refactoring.
