feat: making all vue2 reactive object be valid isReactive

[pikax]

fix #517

Simplifying the logic of isReactive now every valid reactive v2 object will be a valid isReactive object.

The only issue with this is isReactive(obj) === true won't mean auto-unwrapping

const obj = Vue.observable({ a: ref(1) })
const reactiveObj = reactive({a: ref(1) })

isReactive(obj) // true

isReactive(reactiveObj) // true


obj.a // {value:1}
reactiveObj.a // 1

Suggested change

	return (
	(obj &&
	typeof obj === 'object' &&
	'__ob__' in obj &&
	!obj.__ob__.__raw__) ||
	false
	)
	return Boolean(obj?.__ob__ && !obj.__bo__?.__raw__)

Suggested change

	return obj && typeof obj === 'object' && '__ob__' in obj && obj.__ob__.__raw__
	return Boolean(obj?.__ob__?.__raw__)

Do we need this? I think we can make the function arg to (obj: any): T and get rid of those as any then.

Suggested change

	((observed as any).__ob__ && (observed as any).__ob__.value) || observed
	(observed as any)?.__ob__?.value) || observed

Let's put __props_reactive__ inside src/utils/symbols.ts instead of a magic string 😄

Sorry wrong button 😅
