Setting up the different tools for development can be hard for new contributors. This commit adds a Nix flake that provides a reproducible development environment which is easy to set up and ensures consistent code style across all subprojects. The initial flake contains `git`, `pre-commit`, `which` and `bazelisk` wrapped as a `bazel` executable. Dependencies like Rust, Scala etc may be added in the `packages` attribute in the future. The current pre-commit configuration is a no-op. Future commits may enable the currently disabled parts of `pre-commit-hooks.nix` for a gradual transition. Supports `(x86_64|aarch64) (Linux|MacOS)` systems.
