Remarks

When serializing and deserializing types using the options instance, metadata for the types will be fetched from the context instance.

The methods supports adding multiple contexts per options instance. Metadata will be resolved in the order of configuration, similar to how Combine(IJsonTypeInfoResolver[]) resolves metadata.
