Add response options to json and redirect helper bindings

[tom-sherman]

https://remix.run/docs/en/v1/api/remix#http-helpers

Example:

// We can bikeshed the `withResponse` suffix
let jsonWithResponse: ({..}, Webapi.Fetch.ResponseInit.t) => Webapi.Fetch.Response.t
let redirectWithResponse: (string, Webapi.Fetch.ResponseInit.t) => Webapi.Fetch.Response.t

This is currently blocked by the lack of ResponseInit.make and/or Response.make functions in rescript-webapi
