fix(transformer/module_runner): hoist export (#10347)

Aligning with vitejs/vite#18983

I manually verified the test case output matches with the ones in Vite repo.

~I add a new TODO about "export default" getter, but this difference existed already. I plan to fix this separately.~ (EDIT: It turned out Vite's transform is the wrong one vitejs/vite#19834.)
