fix: support basename in static routers

[brophdawg11]

Adds support for basename to static data routers. We accept it up front in createStaticHandler, and then persist it through createStaticRouter/StaticRouterPRovider

Sample usage:

let { query } = createStaticHandler(routes, { basename: '/base '});
let context = await query(request);
let router = createStaticRouter(routes, context);

return ReactDOMServer.renderToString(
  <StaticRouterProvider router={router} context={context} />
);

To align with <RouterProvider> we no longer accept a basename as a prop, we inherit from the router passed to it. In the SSR case, that further inherits from the static handler.
