feat: proxyRefs method and ShallowUnwrapRefs type

[pikax]

vuejs/core#1682

[pikax]

this is caused because the props are marked as raw

Open for suggestions

Guess we can mark the props to shallow reactive and change the test to only tests the top-level toRefs, just like you mentioned in the limitation part?

Props are already reactive, only the nested ref are not

composition-api/test/setup.spec.js

Lines 336 to 371 in 030d02c

	it('toRefs(props) should not warn', async () => {
	let a
	const child = {
	template: `<div/>`,
	props: {
	r: Number,
	},
	setup(props) {
	a = toRefs(props).r
	},
	}
	const vm = new Vue({
	template: `<child :r="r"/>`,
	components: {
	child,
	},
	data() {
	return {
	r: 1,
	}
	},
	}).$mount()
	expect(a.value).toBe(1)
	vm.r = 3
	await Vue.nextTick()
	expect(a.value).toBe(3)
	expect(warn).not.toHaveBeenCalled()
	})

I think it's fine by leaving a note in the limitation for this.
