buffet: Change shared ownership of types/values to exclusive

In order to support array types in Buffet's type system, PropValue
must maintain a strong reference to the underlying PropType since
the array elements will have their own type reference and the current
implementation of using raw pointer for this isn't going to work.
In order to resolve this I had to make a lot of changes to the object
ownership inside Buffet's type system. I made it possible for both
PropType and PropValue to make a deep copy of itself using their
Clone() methods. Because of this now it is possible to have exclusive
ownership of objects and I got rid of most of shared pointer usage in
ObjectSchema, PropType and PropValue.
