changelogs are docs (backport #10354)

We don't mark changelogs as documentation, so CI unnecessarily
does full checks when we add changelogs. Correct this.

NOTE: we only accept changelog files from top-level subdirectories.
There are changelog files in various tests that must be considered
to be "code".

Backport #10448: try to run check-sdist on the right ghcs

(cherry picked from commit 6a2b5a75)

There's little point in having a skip-on-docs trigger if there's
no alternative, cf. the comment in validate.yml.

* sync `validate.yml` with `master`

Too many backorts in the wrong order = mayhem
Giving up on Apple AArch64, `cabal-tests` hates it

* fixup! Merge branch '3.14' into sync-validate.yml-3.14

* Make Cabal-hooks version track Cabal version

As pointed out in #10412, it isn't currently feasible to version the
Cabal-hooks version separately from Cabal due to the large amount of
re-exports (in particular the LocalBuildInfo type and its dependencies).

For the time being, we will version Cabal-hooks along with the major
Cabal library version.

* Update Cabal-hooks/changelog.md

(cherry picked from commit e7bc62be)

* fix cabal install --program-suffix/prefix (fix #10290 and #10476)

When checking for existing installations, cabal would not account for
an affix (suffix or prefix). So, if you had a `hello` binary installed, installing a
second one with a non-empty affix (a perfectly legal operation) would
fail.

The reason seemed to be a typo in
09c04e9a, which passed the arguments to
the Symlink structure in a wrong order.

When failing to install a binary because of an existing one, cabal would
report suffix-less existing target even if a suffix was set.

* Add regression tests for overwrite policies and porgram-affixes

Add regression tests for the `program-prefix` and `program-suffix` flags
combined with the overwrite-policy.
In short, the overwrite-policy needs to take potential program affixes
into account when deciding whether it will need to overwrite a program
path during installation.

Backport #10464: Bump base bound to 4.21 for GHC 9.12

(cherry picked from commit a8d1a5a4)

switch validate to 22.04 for now (backport #10445)

`validate-old-ghcs` doesn't work on 24.04, which GHA just updated
to; and it uses build artifacts from the earlier steps, so for now
the whole thing needs to be downgraded to get thinsg working. We
must address this properly later.

(cherry picked from commit 85f0f0c6)

Backport #10468: add new options for ghc 9.12

- ghc 9.12 adds several new command line options, divided between
  `LANGUAGE`s (already added), warnings, new preprocessor control options,
  and compilation control options. Two options needed to be added to the
  list of options requiring `Int` parameters.

  The new options, excluding warning and language options, are:

  * `-fexpose-overloaded-unfoldings`
  * `-fmax-forced-spec-args=N`
  * `-fno-expose-overloaded-unfoldings`
  * `-fno-object-determinism`
  * `-fobject-determinism`
  * `-fwrite-if-compression=N`
  * `-optCmmP…`
  * `-optJSP…`
  * `-pgmCmmP`
  * `-pgmJSP`

  As they all affect compilation and store hashes, the only necessary
  change was to list the two numeric options so they will be parsed
  correctly. To the best of our understanding, `-pgm*` and `-opt*`
  options are already handled as a group.
