This change would allow `Void` to be used deeper in module graph.
For example exported from `Prelude` (though that might be already
possible).
Also this change includes a change `stimes @Void _ x = x`,
https://github.com/haskell/core-libraries-committee/issues/95
While the above is not required, maintaining old stimes behavior
would be tricky as `GHC.Base` doesn't know about `Num` or `Integral`,
which would require more hs-boot files.

This patch changes the representation of TyCon so that it has
a top-level product type, with a field that gives the details
(newtype, type family etc), #22458.
Not much change in allocation, but execution seems to be a bit
faster.
Includes a change to the haddock submodule to adjust for API changes.

This subtle bug showed up when compiling a library with 9.4.
See #22491. The bug is present in master, but it is hard to
trigger; the new regression test T22491 fails in 9.4.
The fix was easy: just add a missing varToCoreExpr in
etaBodyForJoinPoint.
The fix is definitely right though!
I also did some other minor refatoring:
* Moved the preInlineUnconditionally test in simplExprF1 to
before the call to joinPointBinding_maybe, to avoid fruitless
eta-expansion.
* Added a boolean from_lam flag to simplNonRecE, to avoid two
fruitless tests, and commented it a bit better.
These refactorings seem to save 0.1% on compile-time allocation in
perf/compiler; with a max saving of 1.4% in T9961
