chore: remove Rust workspace

[samuelvanderwaal]

This PR removes Rust work spaces from the repo to decouple project dependencies from each other and make things more flexible. It also modifies and cleans up some tests in order to get CI to pass and makes some CI fixes and improvements.

The big change here regarding BPF tests is to replace the ../../target/deploy folder with a custom test-programs folder in the project root and add a build script that automates installing these dependent programs.

Looks good in general, just had a question about a few things and obviously I wouldn't be aware of things that were missed (since they don't show in the diff).
My main concern is about all these code updates, but maybe they were needed due to some lib upgrades?

I'm not crazy about putting so many unrelated changes in one PR but everything looks correct.

Understandable, but let me refer you to this diagram so you can understand my last couple weeks.
