[Coop] ves_icall_property_info_get_default_value. (mono/mono#16614)

This includes resolving a somewhat deep problem involving
a void* that is usually to a int/float, but can be a MonoObject** or at least MonoString**.
An additional MonoStringHandleOut parameter is pass around to address this.
Perhaps it should be MonoObjectHandleOut for more generality.
