refactor(tvix/eval): use Clap for arg+env parsing r/4911
Refactor the environment variable and argument parsing for the tvix repl to use Clap instead of doing things ad-hoc, and thread through options obtained from environment variables via explicit arguments rather than obtaining them from the environment as they're needed. This makes adding more flags more sustainable, and also makes the binary fully self-documenting, including supported env vars, via `--help`.
