 Since a9c93bdd8b027d6de09a3eada7721e7fd2d3e050 / #10970 GHC is able to
 generate `MIN_VERSION_...` and `VERSION_...` natively without Cabal's
 help.

 Currently, this feature is currently triggered by `-hide-all-packages`.
 However, additionally, it seems reasonable to be able to control this more
 explicitly. E.g. either to be able to explicitly disable even if `-hide-
 all-packages` implicitly enabled the macros, as well as be able to
 explicitly request  macro generation for currently visible packages even
 without any `-hide-all-package`/`-package` flags.
