Improve the Server Actions SWC transform (part 2)

[shuding]

This fills the last piece in the puzzle and it's based on #61001. In #61001 we covered the case of nested Server Action definition in a non "use server" file. And this PR extends that to a "use server" file so exported values are automatically handled just like before, but any other definitions including nested ones will be hoisted and marked correctly now.

'use server'

let a, f

export async function action0(b, c, ...g) { // <- Handled like before.
  return async function action1(d) {        // <- Renamed, marked and hoisted.
    'use server'
    let f
    console.log(...window, { window })
    console.log(a, b, action2)

    async function action2(e) {             // <- Renamed, marked and hoisted.
      'use server'
      console.log(a, c, d, e, f, g)
    }

    return [
      action2,
      async function action3(e) {           // <- Renamed, marked and hoisted.
        'use server'
        action2(e)
        console.log(a, c, d, e)
      },
    ]
  }
}

Closes NEXT-2491
