CI: Allow hadrian-ghc-in-ghci to run in nightlies

Since lint-submods doesn't run in nightlies, hadrian-ghc-in-ghci needs
to mark it as "optional" so it can run if the job doesn't exist.

Fixes #22396.

Minor refactor around FastStrings

Pass FastStrings to functions directly, to make sure the rule
for fsLit "literal" fires.

Remove SDoc indirection in GHCi.UI.Tags and GHC.Unit.Module.Graph.

Bump unix submodule to 2.8.0.0

Also bumps process and ghc-boot bounds on unix.

For hadrian, when cross-compiling, we add -Wwarn=unused-imports
-Wwarn=unused-top-binds to validation flavour. Further fixes in unix
and/or hsc2hs is needed to make it completely free of warnings; for
the time being, this change is needed to unblock other
cross-compilation related work.

Define `Infinite` list and use where appropriate.

Also add perf test for infinite list fusion.

In particular, in `GHC.Core`, often we deal with infinite lists of roles. Also in a few locations we deal with infinite lists of names.

Thanks to simonpj for helping to write the Note [Fusion for `Infinite` lists].

Fix TypeData issues (fixes #22315 and #22332)

There were two bugs here:

1. Treating type-level constructors as PromotedDataCon doesn't always
   work, in particular because constructors promoted via DataKinds are
   called both T and 'T. (Tests T22332a, T22332b, T22315a, T22315b)
   Fix: guard these cases with isDataKindsPromotedDataCon.

2. Type-level constructors were sent to the code generator, producing
   things like constructor wrappers. (Tests T22332a, T22332b)
   Fix: test for them in isDataTyCon.

Other changes:

* changed the marking of "type data" DataCon's as suggested by SPJ.

* added a test TDGADT for a type-level GADT.

* comment tweaks

* change tcIfaceTyCon to ignore IfaceTyConInfo, so that IfaceTyConInfo
  is used only for pretty printing, not for typechecking. (SPJ)

Fire RULES in the Specialiser

The Specialiser has, for some time, fires class-op RULES in the
specialiser itself: see
   Note [Specialisation modulo dictionary selectors]

This MR beefs it up a bit, so that it fires /all/ RULES in the
specialiser, not just class-op rules.  See
   Note [Fire rules in the specialiser]
The result is a bit more specialisation; see test
   simplCore/should_compile/T21851_2

This pushed me into a bit of refactoring.  I made a new data types
GHC.Core.Rules.RuleEnv, which combines
  - the several source of rules (local, home-package, external)
  - the orphan-module dependencies

in a single record for `getRules` to consult.  That drove a bunch of
follow-on refactoring, including allowing me to remove
cr_visible_orphan_mods from the CoreReader data type.

I moved some of the RuleBase/RuleEnv stuff into GHC.Core.Rule.

Metric Decrease:
    T9961

Make indexError work better

The problem here is described at some length in
Note [Boxity for bottoming functions] and
Note [Reboxed crud for bottoming calls] in GHC.Core.Opt.DmdAnal.

This patch adds a SPECIALISE pragma for indexError, which
makes it much less vulnerable to the problem described in
these Notes.

(This came up in another line of work, where a small change made
indexError do reboxing (in nofib/spectral/simple/table_sort)
that didn't happen before my change.  I've opened #22404
to document the fagility.

Fix DsUselessSpecialiseForClassMethodSelector msg

The error message for DsUselessSpecialiseForClassMethodSelector
was just wrong (a typo in some earlier work); trivial fix
