feat: something like Svelte actions

Is your feature request related to a problem? Please describe. Not applicable.

Describe the solution you’d like I’d like to use something like Svelte actions in Million, e.g.:

// This is an action
const tooltip = (node, { text }) => {
  // Mount the tooltip (i.e. create)

  return {
    update: ({ text }) => {
      // Update the tooltip with its new text
    },
    destroy: () => {
      // Unmount the tooltip
    },
  }
}

// This is the action being used
html`<button ${tooltip({ text: 'Some explanation' })}>Do something</button>`

Describe alternatives you’ve considered Maybe it can be implemented with a driver? Not sure yet, I discovered Million less than 24h ago.

create: (node, newVNode, oldVNode) => ...
