[ParseableInterface] Add module arguments if using supplemental output maps

Currently, the check for whether to serialize parseable interface
arguments doesn't handle the case where a supplementary output file map
is used, preferring only to check if the frontend is passed
`-emit*interface`. Instead, check if the frontend inputs and outputs
contains a parseable interface, and use that to determine if we need to
save args.

This also puts `-module-link-name` in the parseable interface arg list.
