Fixes to dealing with the export of mainwip/T19397-backport
It's surprisingly tricky to deal with 'main' (#19397). This
patch does quite bit of refactoring do to it right. Well,
more-right anyway!
The moving parts are documented in GHC.Tc.Module
Note [Dealing with main]
Some other oddments:
* Rename tcRnExports to rnExports; no typechecking here!
* rnExports now uses checkNoErrs rather than failIfErrsM;
the former fails only if rnExports itself finds errors
* Small improvements to tcTyThingCategory, which ultimately
weren't important to the patch, but I've retained as
a minor improvement.
