 ghci: fixity declarations for infix data constructors (#10018)

 Declaring a custom fixity for an infix data constructor should work:

     Prelude> data Infix a b = a :@: b; infixl 4 :@:

 This is a followup to #2947, which handled fixity declarations in ghci
 statements (e.g. let add = (+); infixl 6 `add`).

 Support for declarations (data, type, newtype, class, instance,
 deriving, and foreign) was added to GHCi in #4929.
