… version

In #278074 I removed `exception`
completely. But `nixpkgs` has a version of `exceptions we could use.
Let's enable that instead.

haskell.packages.ghc865Binary.exceptions: restore package, use 0.10.7…

Before the change an attempt to instantiate `stm` package failed as:

    $ nix build --no-link -f. haskell.packages.ghcjs.stm
    error:
       … in the left operand of the update (//) operator

       Did you mean stm_2_5_3_0?

Files like `pkgs/development/haskell-modules/configuration-ghc-8.10.x.nix`
assume `ghc` always has an `llvmPackages` attribue. Let's expose `null`
value from `ghcjs` to allow it's propagation.

This fixes package evaluation for `ghcjs` packages.

We're opting for the strategy of providing the most up to date version
llvm-ffi supports which works out well enough, as nixpkgs also tries to
be quite up to date with its LLVM version (and also uses LLVM 16 as the
default).

No longer needed by stack.

- Use hfinal where possible
- Move overrides out of custom overlay where possible

dhall suddenly appeared in Stackage LTS 21 at 1.41.* which we don't
necessarily want, as we were using 1.42.* before. It is much easier to
revert this downgrade due to other packages (not in Stackage LTS) we are
shipping, like dhall-nix, dhall-nixpkgs and hnix.

For GHC 9.6 and 9.8 we can use the Cabal library bundled with GHC since
it matches the requested version. This can prevent inconsistent
dependencies later in e.g. haskell-language-server.

For lower versions we may need to jailbreak and downgrade Cabal to which
upstream seems to be open:

> We need to pin a single major version of Cabal here because the main
> reason we use Cabal is for its list of extensions. Later versions have
> strictly more extensions, and we'll have missing patterns if we try to
> support more than one major version. If this causes problems in
> practice let's revisit this decision and come up with another

Alternatively, hls-stan-plugin can be disabled.

hls-stan-plugin is not buildable with GHC >= 9.2.4 && < 9.4, so we have
no GHC from the 9.2 series that would support this plugin.

All versions have this patch that conditionally enables support for
template-haskell >= 2.16, so we can fold them into one.

Support for GHC 9.0 was dropped in this version, so we can no longer
ship it.

haskellPackages.ircbot, haskellPackages.bytestring-conversion: unbreak

haskellPackages.double-conversion: don't use vendored library

Clean up override for removed version.

Sorry, this is a bit of a draw the rest of the owl commit. Upgraded
where sensible/possible, all jailbreaks note the bounds issues which are
luckily relatively boring (base and friends).

Removed overrides are mostly stale overrides from configuration-head.nix
that don't work anymore and make little sense with the current package
set anyways.

These packages are too tightly coupled to GHC/Cabal

Unfortunately we have a disagreement between Stackage LTS and what
pandoc needs for typst-symbols.
