Add a -fprint-axiom-incomps option (#15546)
Supply branch incomps when building an IfaceClosedSynFamilyTyCon
`pprTyThing` now has access to incomps. This also causes them to be
written out to .hi files, but that doesn't pose an issue other than a
more faithful bijection between `tyThingToIfaceDecl` and `tcIfaceDecl`.
The machinery for displaying axiom incomps was already present but not
in use. Since this is now a thing that pops up in ghci's :info the
format was modified to look like a haskell comment.
Documentation and a test for the new feature included.
