Open menu with standard button instead of MenuButton

[ThomasKientz]

To open a Menu we are forced to add a MenuButton. That's not very flexible as we can not use a standard button or a custom component (without rewriting it to implement MenuButton).

One way to address this would be to expose api.openMenu() as a slot prop. It would look like this :

<Menu v-slot="{ openMenu }">
  <button @click="openMenu()">Open</button>
</Menu>

Even better, Menu could expose event handlers and attributes (inspired from Vuetify's VMenu)

<menu>
  <template v-slot:activator="{ on, attrs }">
    <button v-bind="attrs" v-on="on">Open</button>
  </template>
</menu>

What do you think ?
