Finish apply_dist()

[duckinator]

EDIT (2025-03-13): I was reminded of this PR earlier today, and wanted to leave a quick note for anyone who may try picking up this work in the future.

You can definitely split this up into smaller PRs, I just didn't have the time to do so before my contract ended. You will likely need to mark things with #[allow(dead_code)] for it to be mergeable.

This PR is functional and has unit tests for each part that was split into its own file.

Since I tried to make each file self-contained, you can make PRs doing the following:

1. Add pretty_assertions dep (Cargo.toml, Cargo.lock, cargo-dist/Cargo.toml)
2. Add cargo-dist/src/init/apply_dist/helpers.rs
3. Add cargo-dist/src/init/apply_dist/artifacts.rs
4. Add cargo-dist/src/init/apply_dist/builds.rs
5. Add cargo-dist/src/init/apply_dist/ci.rs
6. Add cargo-dist/src/init/apply_dist/hosts.rs
7. Add cargo-dist/src/init/apply_dist/installers.rs
8. Add cargo-dist/src/init/apply_dist/publishers.rs
9. Add cargo-dist/src/init/apply_dist/mod.rs + remove cargo-dist/src/init/apply_dist.rs
10. Update cargo-dist/src/init/mod.rs.

If you do that, and they all are merged, you can rebase #1763 off main and the diff will be way smaller.

original description

NOTE: The errors are due to dist::init::apply_dist::apply() never being called outside of the test suite.

---

This PR is functional and has unit tests for each part that was split into its own file. I knew this PR was going to be distressingly large, so I tried to design it so each part could be treated entirely self-contained.

The exception is cargo-dist/src/init/apply_dist/mod.rs, which pulls everything else in that directory together.

There's also cargo-dist/src/init/mod.rs, but that's tiny.

There is definitely room for refactoring in some spots, because I learned a lot of tricks as I got farther into it. I don't think it's worth adding even more churn to this PR, though.

We ultimately elected not to ship the config 1.0 branch. The branch this was meant to be applied to can be found in the config_1_0 branch.
