`collection_type_impl::serialize_mutation_form` became `collection_mutation(_view)_description::serialize`. Previously callers had to cast their data_type down to collection_type to use serialize_mutation_form. Now it's done inside `serialize`. In the future `serialize` will be generalized to handle UDTs. `collection_type_impl::deserialize_mutation_form` became a free standing function `deserialize_collection_mutation` with similiar benefits. Actually, noone needs to call this function manually because of the next paragraph. A common pattern consisting of linearizing data inside a `collection_mutation_view` followed by calling `deserialize_mutation_form` has been abstracted out as a `with_deserialized` method inside collection_mutation_view. serialize_mutation_form_only_live was removed, because it hadn't been used anywhere.
