Introduce TcRnWithHsDocContext (#22346)
Before this patch, GHC used withHsDocContext to attach an HsDocContext
to an error message:
addErr $ mkTcRnUnknownMessage $ mkPlainError noHints (withHsDocContext ctxt msg)
The problem with this approach is that it only works with
TcRnUnknownMessage. But could we attach an HsDocContext to a
structured error message in a generic way? This patch solves
the problem by introducing a new constructor to TcRnMessage:
data TcRnMessage where
...
TcRnWithHsDocContext :: !HsDocContext -> !TcRnMessage -> TcRnMessage
...
