Write information about non-reinstallable packages to a file in the libdir

This the GHC ticket for implementing the interface for: https://github.com/haskell/cabal/issues/10087

Since the set of reinstallable packages will now vary depending on GHC version, we should communicate that to Cabal.

An easy way to do that is write a file with a list of non-reinstalable packages into the libdir. If Cabal sees that, then it uses that list, otherwise it uses the old default.

Maybe we could add this to the settings file?
