Allow define store options in setup stores

[sontd-nals]

What problem is this solving

Currently, the option stores are able to add extra options when defining a store, for example:

  export const useCounterStore = defineStore('counter', {
+   persist: true,
    state: () => ({ count: 0, name: 'Eduardo' }),
    getters: {
      doubleCount: (state) => state.count * 2,
    },
    actions: {
      increment() {
        this.count++
      },
    },
  })

But there is no way to define the options when using the setup store.

Proposed solution

Implement a new function allowing to define the store options when using the setup store, just like vue defineOptions macro

  export const useCounterStore = defineStore('counter', () => {
+   defineStoreOptions({ persist: true })
    const count = ref(0)
    const name = ref('Eduardo')
    const doubleCount = computed(() => count.value * 2)
    function increment() {
      count.value++
    }
  
    return { count, name, doubleCount, increment }
  })

It's already possible with the second argument:

defineStore('id', () => {}, options)
