Improve RSC plugin to provide better errors

[shuding]

This PR improves the RSC plugin for SWC to throw an error when the "use client" directive is in the top level, but not before other statements / expressions. For example:

Code:

import 'react'

'use client'

Error:

The "use client" directive must be placed before other expressions. Move it to the top of the file to resolve this issue.
