/**
* @internal
*
* Makes an Apollo Client hook "wrappable".
* That means that the Apollo Client instance can expose a "wrapper" that will be
* used to wrap the original hook implementation with additional logic.
* @example
*
* ```tsx
* // this is already done in `@apollo/client` for all wrappable hooks (see `WrappableHooks`)
* // following this pattern
* function useQuery() {
*   return wrapHook('useQuery', _useQuery, options.client)(query, options);
* }
* function _useQuery(query, options) {
*   // original implementation
* }
*
* // this is what a library like `@apollo/client-react-streaming` would do
* class ApolloClientWithStreaming extends ApolloClient {
*   constructor(options) {
*     super(options);
*     this.queryManager[Symbol.for("apollo.hook.wrappers")] = {
*       useQuery: (original) => (query, options) => {
*         console.log("useQuery was called with options", options);
*         return original(query, options);
*       }
*     }
*   }
* }
*
* // this will now log the options and then call the original `useQuery`
* const client = new ApolloClientWithStreaming({ ... });
* useQuery(query, { client });
* ```
* 
* @deprecated This is an internal API and should not be used directly. This can be removed or changed at any time.
