feat: improve route access

BREAKING CHANGE: `useRoute` now retrieves a reactive RouteLocationNormalized instead of a Ref<RouteLocationNormalized>.
  This means there is no need to use `.value` when accessing the route. You still need to wrap it with `toRefs` if you want to expose parts of the route:
  ```js
  setup () {
    return { params: toRefs(useRoute()).params }
  }
  ```
