请在vue-router3版本中加入useRoute和useRouter钩子函数。

Version

3.6.5

Steps to reproduce

因为vue2.7是支持组合式API的，但是又只支持vue-router3，vue-router3 又没有实现useRoute和useRouter钩子函数。这就导致我们自己实现的钩子函数useRoute和useRouter无法在watch中被监听到变化，主要是useRoute().query的变化。
我们自己封装的钩子如下：
import { getCurrentInstance } from 'vue'
/** this.$route替换方案 /
export function useRoute() {
const { proxy } = getCurrentInstance()
const route = proxy.$route
return route
}
/* this.$router替换方案 */
export function useRouter() {
const { proxy } = getCurrentInstance()
const router = proxy.$router
return router
}

What is expected?

想要watch能监听到useRoute().query的变化。
在vue-router3中加入useRoute和useRouter钩子函数。

What is actually happening?

watch能不能监听到替代方案useRoute().query的变化。

They are already there:

import { useRouter } from 'vue-router/composables'

excellent!
import { useRouter } from 'vue-router/composables' it can be watch and work.
