<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Introduce and use DerivClauseTys (#18662)

This switches `deriv_clause_tys` so that instead of using a list of

`LHsSigType`s to represent the types in a `deriving` clause, it now

uses a sum type. `DctSingle` represents a `deriving` clause with no

enclosing parentheses, while `DctMulti` represents a clause with

enclosing parentheses. This makes pretty-printing easier and avoids

confusion between `HsParTy` and the enclosing parentheses in

`deriving` clauses, which are different semantically.

Fixes #18662.
