Add option to force calling matchRoutes() on every render (pre-7.1.4 behaviour)

[leeleahulkcs]

react-router 7.1.4 includes a change to Optimize route matching by skipping redundant matchRoutes calls when possible (#12800, #12882). Effectively, this "caches" the first result of matchRoutes() and offers no option to clear or disable this cache.

I have an application that dynamically creates a routes structure. This structure is then passed to createBrowserRouter() and that return value is passed to <RouterProvider/>. In the entire application, there is only one instance/call to createBrowserRouter() and <RouterProvider/>.

As of version 7.1.4, the ability to dynamically change the routes without reloading the entire application is no longer possible.

I would like to request that createBrowserRouter() be modified to accept flag which (when set truthy) will force matchRoutes() to be called (thus reverting to pre-7.1.4 behaviour).

The specific line(s) which need to check this flag would be https://github.com/remix-run/react-router/blob/react-router%407.1.4/packages/react-router/lib/hooks.tsx#L538-L548.
