Expose list of wired-in units in --info

This lets Cabal know which packages are wired-in.
In turn Cabal can use this information to determine which packages
should be re-installable.
Previously this was a fixed list that was hard-coded into Cabal.

See: <https://github.com/haskell/cabal/issues/10087>

Resolves #25282
