chez-racket: init at 2021-12-11

[L-as]

Motivation for this change

This is basically Chez Scheme but better, notably it supports aarch64-linux (and likely aarch64-darwin too!).
This can be used to make Idris 2 work on more platforms with its Chez Scheme backend, albeit it is not done in this PR.

Things done

I've added chez-racket as a separate directory with its own files, since it's a permanent fork.
The only common part is the setup hook.

It would be great if someone on aarch64-darwin could test this.

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• 21.11 Release Notes (or backporting 21.05 Relase 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.

Bump

I've fixed all the problems and in the process also added support for cross-compilation!

While I'm not able to test this myself, it seems to me that the chance that this is a bug upstream is somewhat high.

I made an issue upstream: racket/ChezScheme#43

It appears all four platforms work, so I'm going to merge this.
