Add a Nix flake along with a package derivation (default.nix) and dev shell (shell.nix). Update hotglsl.

These can be ignored by most users, but will be useful for Nix folks and may help to simplify our CI a little.

The default.nix can also be used as a CI-checked reference of what system dependencies and env vars are required on Linux and macOS.

Tested successfully on x86_64-linux and aarch64-darwin.

TODO

[x] Rebase onto bevy-refactor branch.
[x] Simplify CI dependency installation with Nix.
[x] Add section to Contributing.md about Nix.

The hotglsl crate was updated to 0.2 in order to switch from the glsl-to-spirv crate to the pure-Rust naga removing the need for some system deps like libclang.

@mitchmindtree Just had to do this for bevy which was kinda annoying https://github.com/nannou-org/nannou/pull/952/commits/e5fcbe95f37ca9171b8826dd38e416c29d33d0ee. The simplest fix would be a composite action but I could be convinced to run nix in ci. ^^

OK I've had a go at simplifying the CI a little and added a "Nix Shell" contributing chapter!
