Write event.response.headers to returned Responses

[Brendonovich]

If a Response is returned from an API route or server function, any headers written via @solidjs/start/http including useSession are not passed on. This writes headers from getRequestEvent().response to the returned response, if the header doesn't already exist on the returned response.
In the case of redirects being returned, we clone the response in case it is immutable (such as those returned from Response.redirect)
