Merge GHC 9.4 into `main`

Backport 9-4: Fix hyperlinks to external items and modules (#1482)

Jade Lovelace authored 3 years ago and Douglas Wilson committed 2 years ago

Fixes #1481.

There were two bugs in this:
* We were assuming that we were always getting a relative path to the
  module in question, while Nix gives us file:// URLs sometimes. This
  change checks for those and stops prepending `..` to them.
* We were not linking to the file under the module. This seems
  to have been a regression introduced by #977. That is, the URLs were
  going to something like
  file:///nix/store/3bwbsy0llxxn1pixx3ll02alln56ivxy-ghc-9.0.2-doc/share/doc/ghc/html/libraries/base-4.15.1.0/src
  which does not have the appropriate HTML file or fragment for the item
  in question at the end.

There is a remaining instance of the latter bug, but not in the
hyperlinker: the source links to items reexported from other modules are
also not including the correct file name. e.g. the reexport of Entity in
esqueleto, from persistent.

NOTE: This needs to get tested with relative-path located modules. It seems
correct for Nix based on my testing.

Testing strategy:

```
nix-shell '<nixpkgs>' --pure -A haskell.packages.ghc922.aeson
mkdir /tmp/aesonbuild && cd /tmp/aesonbuild
export out=/tmp/aesonbuild/out
genericBuild

ln -sf $HOME/co/haddock/haddock-api/resources .
./Setup haddock --with-haddock=$HOME/path/to/haddock/exec --hyperlink-source
```

(cherry picked from commit ab53ccf0)

* Follow hlint suggestion: redundant $.

* Remove $ and surplus blank lines in Operators.

* Follow hlint suggestion: unused LANGUAGE pragma.

* Ignore within modules to pass linting and pass tests.

Redo the counts available with the --default option.

Fix #783 Don't show button if --quickjump not present

* Render module tree per package in the content page

When rendering content page for multiple packages it is useful to split
the module tree per package.  Package names in this patch are inferred
from haddock's interface file names.

* Write PackageInfo into interface file

To keep interface file format backward compatible, instead of using
`Binary` instance for `InterfaceFile` we introduce functions to
serialise and deserialise, which depends on the interface file version.

* Pin GHC version before creating the freeze file

* Use newest action versions

* Improve caching

* Avoid unnecessarily reinstalling GHC

* Use GHC 9.2.2 for CI

This is also consistent with how html index is build.  See
haskell/cabal#7669 for rationale behind this decision.

* Version bump 2.26.1

We extended format accepted by `--read-interface` option, which requires
updating the minor version.

* Update documentation of --read-interface option

This is useful when one wishes to `--gen-contents` when rendering
multiple components, but one does not want to render all modules.  This
is in particular useful when adding base package.
