Store RdrName rather than OccName in Holes
In #20472 it was pointed out that you couldn't defer out of scope but
the implementation collapsed a RdrName into an OccName to stuff it into
a Hole. This leads to the error message for a deferred qualified name
dropping the qualification which affects the quality of the error
message.
This commit adds a bit more structure to a hole, so a hole can replace a
RdrName without losing information about what that RdrName was. This is
important when printing error messages.
I also added a test which checks the Template Haskell deferral of out of
scope qualified names works properly.
Fixes #22130
