Consider removing RelaxedLayout and friends

These three parsing-related language extensions were introduced some time ago yet are likely not used in the wild as they still are not registered in Cabal's language extension list (which Hackage uploads are checked against, see #8176 (closed)),

  • RelaxedLayout (introduced in 7.2, prompted by #1060 (closed))
  • AlternativeLayoutRule (introduced in 7.0, reason unknown)
  • AlternativeLayoutRuleTransitional (introduced in 7.0, reason unknown)

As far as I can tell no one knows the status of these, nor are they listed in the users guide.

We should ask the community whether they would mind seeing these extensions vanish and remove them if not. If so then we should see to it that they are registered properly with Cabal so they can be used on Hackage.
