Provide a more convinient way of developing rustc on NixOS
This PR adds envrc files which, once symlinked as `.envrc` will activates a dev shell from `src/tools/nix-dev-shell/flake.nix` or `src/tools/nix-dev-shell/shell.nix`.
This is based on
- [Current rustc dev guide recommendation for NixOS](https://rustc-dev-guide.rust-lang.org/building/suggested.html?highlight=nix#using-nix-shell)
- https://github.com/oxalica/rust-overlay?tab=readme-ov-file#use-in-devshell-for-nix-develop
- [Nora's `x` nix package](26ea68e1a0/custom-pkgs/x)
- https://github.com/rust-lang/rustup/pull/2891
- [Direnv: use flake/nix according to availability](https://discourse.nixos.org/t/direnv-use-flake-nix-according-to-availability/29825)
This is something that I plan to use personally, but I thought it might be worth upstreaming :)

# This file should only ignore things that are generated during a `x.py` build,
|
|
# generated by common IDEs, and optional files controlled by the user that
|
|
# affect the build (such as config.toml).
|
|
# In particular, things like `mir_dump` should not be listed here; they are only
|
|
# created during manual debugging and many people like to clean up instead of
|
|
# having git ignore such leftovers. You can use `.git/info/exclude` to
|
|
# configure your local ignore list.
