Fix parsing & printing of unboxed sums
The pretty-printing of partially applied unboxed sums was incorrect,
as we incorrectly dropped the first half of the arguments, even
for a partial application such as
(# | #) @IntRep @DoubleRep Int#
which lead to the nonsensical (# DoubleRep | Int# #).
This patch also allows users to write unboxed sum type constructors
such as
(# | #) :: TYPE r1 -> TYPE r2 -> TYPE (SumRep '[r1,r2]).
Fixes #20858 and #20859.
