Refactor TypeProperty to better represent ObjectType state

[levimatheri]

Follow up to PR feedback.

With the current ObjectType signature, it's technically possible for AdditionalPropertiesDescription to be non-null even if AdditionalPropertiesType is null. This PR creates a new NamedTypeProperty record that represents a property with a name and a type, which is used for the ObjectType.Properties property.
The TypeProperty record encapsulates the type ref, flags and description, preventing a non-null description with a null type ref being passed into ObjectType.

New ObjectType signature:
public ObjectType(string name, TypeSymbolValidationFlags validationFlags, IEnumerable<NamedTypeProperty> properties, TypeProperty? additionalProperties, Func<ObjectType, FunctionResolver> methodResolverBuilder)
