feat(rsc): support hoisting with runtime wrapper in transformHoistInlineDirective + add callable use cache example

[hi-ogawa]

• part of Support Framework-Owned "use cache" Server Functions #1336

This PR adds hoistRuntime: boolean option to transformHoistInlineDirective, so it allows hoist-exported inline directive functions to have runtime wrapper applied. Still haven't fully verified the exact requirement for use cache in #1246 but this looks like a concrete self-contained step forward with demonstrate-able e2e, so I'm thinking to land this first anyways.

Example:

• Source

function Component() {
  const x = 1

  async function action(y) {
    'use cache'
    return x + y
  }
}

• Transformed with hoistRuntime: false (still the default)

function Component() {
  const x = 1
  const action = __RUNTIME__($$hoist_0_action).bind(null, x) // 👈 runtime in reference site
}

export async function $$hoist_0_action(x, y) {
  'use cache'
  return x + y
}

• Transformed with hoistRuntime: true

function Component() {
  const x = 1
  const action = $$hoist_0_action.bind(null, x)
}

export const $$hoist_0_action = __RUNTIME__($$hoist_0_action$$impl) // 👈 runtime in export site

async function $$hoist_0_action$$impl(x, y) {
  'use cache'
  return x + y
}
