Fix accidental widening of the client.mutate return type when optimisticResponse was present.

Fix result types widened when a query's variables had constant types (e.g. TypedDocumentNode<Data, { type: "main" }>). This caused options such as returnPartialData or errorPolicy to be reported as their widened types (e.g. boolean, ErrorPolicy) instead of the value that was passed which returned the wrong data and dataState types.

Fix issue where unknown options were permitted by TypeScript when passed alongside a valid option to APIs with modern signatures.

Update the return type of refetch, fetchMore and useLazyQuery's execute function on the provided errorPolicy. Previously these APIs all used the default type which typed data as TData | undefined and error as ErrorLike | undefined.
