refactor(web/tvixbolt): buildRustPackage -> crate2nix

With the recent changes to crate2nix and buildRustCrate in nixpkgs it is
now possible to build tvixbolt via crate2nix like we do for other tvix
crates. We can reuse a lot of the customizations done in //tvix in
tvixbolt to avoid repeating ourselves.

A script for serving tvixbolt locally for testing purposes is also
available now through the .serve attribute of tvixbolt.

This change supersedes https://cl.tvl.fyi/c/depot/+/11821.
