Clean up TH's treatment of unary tuples (or, #16881 part two)
!1906 left some loose ends in regards to Template Haskell's treatment
of unary tuples. This patch ends to tie up those loose ends:
* In addition to having `TupleT 1` produce unary tuples, `TupE [exp]`
and `TupP [pat]` also now produce unary tuples.
* I have added various special cases in GHC's pretty-printers to
ensure that explicit 1-tuples are printed using the `Unit` type.
See `testsuite/tests/th/T17380`.
* The GHC 8.10.1 release notes entry has been tidied up a little.
Fixes #16881. Fixes #17371. Fixes #17380.
