proto: change WindowManager child_tokens format

This commit changes the WindowManager's child_tokens field from a
repeated int32 to a repeated IdentifierProto message.

Thus the WindowManager incremental tracing can signal to the ProtoVM
when the list becomes empty, emitting an empty IndentifierProto message.

This is a breaking change, but acceptable as the field is not being used
yet.
