 Add Fixity info for infix types

 Template Haskell allows reification of fixity for infix functions and
 data constructors, and not for infix types. This adds a `Fixity` field
 to the relevant `Info` constructors that can have infix types (`ClassI`,
 `TyConI`, and `FamilyI`).

 I don't think that `VarI` or `PrimTyConI` can be infix, but I could be
 wrong.
