Set isExtendedAttribute during Load()

Set the new optional `isExtendedAttribute` parameter of `AttributeValueCollection.SetValue()` (10c7c09) during `Load()` as part of the `SetIndexedAttributes()` and `SetExtendedAttributes()` extension methods. This ensures that this value is set on the underlying `AttributeValue`, and is available later to detect potential `IsExtendedAttribute` mismatches.
