llvmPackages_17.{clang,tblgen}: fix builds on aarch64

[zvolin]

Fixes #371077

Applies the patch proposed in the llvm issue. The fix will not make it to the llvm itself as they don't accept fixes for old release branches due to the complexity of the process.

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

I tried running nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD" but it wanted to build so many packages that I was afraid of my (limited) disk space

Diff LGTM, I'll spin up an aarch64-linux build tonight after work.

moved new patch next to other clang ones in getVersionFile

there are not many packages which require llvm-17 on aarch64 linux (according to https://malob.github.io/nix-review-tools-reports/nixpkgs:trunk/nixpkgs_trunk_1811789.html) outside of the llvm-17 package set:

• clipbuzz.aarch64-linux
• haskellPackages.llvm-codegen.aarch64-linux
• ly.aarch64-linux
• mepo.aarch64-linux
• mlir_17.aarch64-linux
• rivercarro.aarch64-linux
• zig_0_12.aarch64-linux

and rather use some patch in an unmerged PR which seems non-trivial to verify if it has any unintended side-effects just marking llvm-17 broken on aarch64-linux seems like a better option to me.

It's possible that the nixpkgs-review command tried to rebuild everything that depends on llvm then (without -17).

Makes sense. I lack experience to judge potential side-effects. I needed this change because I tried to use swift 6.0 but faced other issues with it further down the road and resigned in favor of docker. Thought I'll just submit a patch as I had it working
