Generic typo detection in RSC directives (#68890)
This PR changes the Server Actions SWC transform, to instead of having a
hard coded list of
`"use server"` directive typos we use a O(len) algorithm to detect
possible mistakes in the directive name. Note that the previous
`.iter()` approach is also theoretically slower O(n * len).
This was cherry-picked from a larger change which will later make this
transform more general and support different directive names (via
configurations).
