Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
Also exposes owner, repo, and other attributes available on the original
monorepoSrc. These attributes were previously hidden behind a
runCommand that consumes monorepoSrc and hides this information away.

Before the change `llvmPackages.bintools.bintools.targetPrefix` was not
present. This exposed as a discrepansy between `binutils` and `llvm`:
`binutils`:
nix-repl> stdenv.cc.bintools.bintools.targetPrefix
""
nix-repl> stdenv.cc.bintools.targetPrefix
""
`llvm`:
nix-repl> pkgsLLVM.stdenv.cc.bintools.targetPrefix
"x86_64-unknown-linux-gnu-"
nix-repl> pkgsLLVM.stdenv.cc.bintools.bintools.targetPrefix
error:
error: attribute 'targetPrefix' missing
As a result some attributes like `pkgsLLVM.actionlint` failed to
evaluate:
$ nix build --no-link -f. pkgsLLVM.actionlint
...
error: attribute 'targetPrefix' missing
at pkgs/development/compilers/ghc/9.4.8.nix:232:46:
231| export READELF="${targetCC.bintools.bintools}/bin/${targetCC.bintools.targetPrefix}readelf"
232| export STRIP="${bintoolsFor.strip}/bin/${bintoolsFor.strip.targetPrefix}strip"
| ^
The change exposes binary prefix the same way as `binutils` does.
