Implement `-f(no-)version-macros` flag for controlling version macro generation
Since a9c93bdd / #10970 (closed) 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.
