primops: Introduce unsafeThawByteArray#

This addresses an odd asymmetry in the ByteArray# primops, which
previously provided unsafeFreezeByteArray# but no corresponding
thaw operation.

Closes #22710

Allow users to override non-essential haddock options in a Flavour

We now supply the non-essential options to haddock using the `extraArgs`
field, which can be specified in a Flavour so that if an advanced user
wants to change how documentation is generated then they can use
something other than the `defaultHaddockExtraArgs`.

This does have the potential to regress some packaging if a user has
overridden `extraArgs` themselves, because now they also need to add
the haddock options to extraArgs. This can easily be done by appending
`defaultHaddockExtraArgs` to their extraArgs invocation but someone
might not notice this behaviour has changed.

In any case, I think passing the non-essential options in this manner is
the right thing to do and matches what we do for the "ghc" builder,
which by default doesn't pass any optmisation levels, and would likewise
be very bad if someone didn't pass suitable `-O` levels for builds.

Fixes #23625

ghc-prim: Link against libatomic

Commit b4d39adbb58 made 'hs_cmpxchg64()' available to all architectures.
Unfortunately this made GHC to fail to build on armel, since armel needs
libatomic to support atomic operations on 64-bit word sizes.

Configure libraries/ghc-prim/ghc-prim.cabal to link against libatomic,
the same way as we do in rts/rts.cabal.

simplifier: Correct InScopeSet in rule matching

The in-scope set passedto the `exprIsLambda_maybe` call lacked all the
in-scope binders. @simonpj suggests this fix where we augment the
in-scope set with the free variables of expression which fixes this
failure mode in quite a direct way.

Fixes #23630

Finish migration of diagnostics in GHC.Tc.Validity

This patch finishes migrating the error messages in GHC.Tc.Validity
to use the new diagnostic infrastructure.

It also refactors the error message datatypes for class and family
instances, to common them up under a single datatype as much as possible.

ci: Enable some more jobs to run in a marge batch

In !10907 I made the majority of jobs not run on a validate pipeline but
then forgot to renable a select few jobs on the marge batch MR.

user_guide/flags.py: python-3.12 no longer includes distutils

packaging.version seems able to handle this fine

ci: Mention ~full-ci label in MR template

We mention that if you need a full validation pipeline then you can
apply the ~full-ci label to your MR in order to test against the full
validation pipeline (like we do for marge).

RTS: declare setKeepCAFs symbol

Commit 08ba8720 failed to declare the dependency of keepCAFsForGHCi on
the symbol setKeepCAFs in the RTS, which led to undefined symbol errors
on Windows, as exhibited by the testcase frontend001.

Thanks to Moritz Angermann and Ryan Scott for the diagnosis and fix.

Fixes #22961

Mark plugins-external as broken on Windows

This test is broken on Windows, so we explicitly mark it as such now
that we stop skipping plugin tests on Windows.

Stop marking plugin tests as fragile on Windows

Now that b2bb3e62 has landed we are in a better situation with
regards to plugins on Windows, allowing us to unmark many plugin tests
as fragile.

Fixes #16405

Misc cleanup

- Remove unused RDR names
- Fix typos in comments
- Deriving: simplify boxConTbl and remove unused litConTbl
- chmod -x GHC/Exts.hs, this seems accidental
