fix: handle v-for + custom directive should trigger unmounted

[linzhe141]

close #12569

try to simulate this case using component

In this issue, if I use a component to simulate this case, vue can trigger the component's onUnmounted hook, because when collecting dynamicChildren, ShapeFlags.COMPONENT is always collected.

core/packages/runtime-core/src/vnode.ts

Line 524 in 833f9ea

(vnode.patchFlag > 0 || shapeFlag & ShapeFlags.COMPONENT) &&

So I think if vnode uses runtime dirctives, it should also be collected into dynamicChildren，Or mark this v-for fragment as not STABLE_FRAGMENT？
