Implement cDAC SosDac API GetCCWData

[Copilot]

Implements ISOSDacInterface::GetCCWData in the cDAC managed layer. The contract surface exposes fine-grained CCW predicates; SOSDacImpl assembles DacpCCWData by composing them directly rather than delegating to a single aggregate contract method.

Contract surface (IBuiltInCOM / BuiltInCOM_1)

New predicate methods (grouped with GetRefCount / IsHandleWeak):

• IsNeutered — CLEANUP_SENTINEL bit in raw ref count
• IsExtendsCOMObject — IsExtendsCom flag on SimpleComCallWrapper
• IsAggregated — IsAggregated flag on SimpleComCallWrapper

New scalar accessors:

• GetCCWAddress(ccw) — navigates to start wrapper via SimpleWrapper→MainWrapper (mirrors C++ GetStartWrapper); any wrapper in the chain is accepted
• GetCCWHandle(ccw) — GC object handle (m_ppThis) from the start wrapper
• GetOuterIUnknown(ccw) — outer IUnknown (m_pOuter) from the shared SimpleComCallWrapper

GetCCWInterfaces reuses the same NavigateToStartWrapper helper.

Data descriptors

Two new fields exposed via cdac_data<>, datadescriptor.inc, and managed Data/ classes:

• ComCallWrapper.Handle (m_ppThis)
• SimpleComCallWrapper.OuterIUnknown (m_pOuter)

Legacy layer (SOSDacImpl)

GetCCWData signature changed from void* data to typed DacpCCWData* data. Implementation composes the struct from individual contract calls:

TargetPointer startCCW = contract.GetCCWAddress(ccwPtr);
TargetPointer handle   = contract.GetCCWHandle(startCCW);
int refCount           = (int)contract.GetRefCount(startCCW);

data->outerIUnknown       = contract.GetOuterIUnknown(startCCW).ToClrDataAddress(_target);
data->handle              = handle.ToClrDataAddress(_target);
data->managedObject       = (handle != TargetPointer.Null ? _target.ReadPointer(handle) : TargetPointer.Null).ToClrDataAddress(_target);
data->ccwAddress          = startCCW.ToClrDataAddress(_target);
data->refCount            = refCount;
data->interfaceCount      = contract.GetCCWInterfaces(startCCW).Count();
data->isNeutered          = contract.IsNeutered(startCCW)         ? BOOL.TRUE : BOOL.FALSE;
data->hasStrongRef        = (refCount > 0) && !contract.IsHandleWeak(startCCW) ? BOOL.TRUE : BOOL.FALSE;
data->isExtendsCOMObject  = contract.IsExtendsCOMObject(startCCW) ? BOOL.TRUE : BOOL.FALSE;
data->isAggregated        = contract.IsAggregated(startCCW)       ? BOOL.TRUE : BOOL.FALSE;
// jupiterRefCount / isPegged / isGlobalPegged always 0/false (non-WinRT path)

Tests

• Unit tests for IsNeutered, IsAggregated, IsExtendsCOMObject, GetCCWAddress (including non-start wrapper navigation), GetCCWHandle (value and null), GetOuterIUnknown (value and zero)
• Dump test exercising the full SOSDacImpl.GetCCWData path against live CCWs
