Refactor: Use workspace dependencies

[lemunozm]

Description

This PR move previous @wischli work (1a45bbe) to its own PR, and extends it to remove any hardcoded path from our codebase in Cargo.toml files.

Changes

• No more paths in any Cargo.toml file except the in the root file.
• Use workspace definitions for [package].
• Removed some unused dependencies.
• Fixed some dependency features

[wischli]

Correcting my own left overs (probably): Some crates still don't fully make use of workspace inheritance. I marked all my findings. Thanks for extracting this already!

[lemunozm]

I forgot to tell that this is still very WIP. I need to update a lot of dependencies

[lemunozm]

Thanks for the reminders @wischli!

The compilation state after this refactor has not changed (manually tested):

• Checking process (no std):
  • ✅ cargo check
  • ❌ cargo check -F runtime-benchmarks
    • It fails with a missing feature issue, but the same issue already appears in main. I think it's because fudge is not setting the correct features (runtime-benchmarks & try-runtime) for its dependencies. Excluding integration tests makes the compilation work.
  • ✅ cargo check --workspace -F runtime-benchmarks --exclude runtime-integration-tests
  • ✅ cargo check -F try-runtime
  • ❌ cargo check -F runtime-benchmarks,try-runtime
    • Same issue as before. Also failing in main
• Testing process (std):
  • ✅ cargo test
  • ❌ cargo test -F runtime-benchmarks
    • Same issue as before. Also failing in main
  • ✅ cargo test --workspace -F runtime-benchmarks --exclude runtime-integration-tests
  • ✅ cargo test -F try-runtime
  • ❌ cargo test -F runtime-benchmarks,try-runtime
    • Same issue as before. Also failing in main

I will merge this PR with the above errors (already in main), but I would try to fix them before moving to polkadot-1.1.0.

[wischli]

I really appreciate that you checked all the compiling possibilities with this and the main branch. I really hope we can fix all of that with the Polkadot v1.1.0 upgrade!

This PR looks super clean and ready to be merged to me 🚀

[mustermeiszer]

Thanks for the cleaning!

[cdamian]

Nit - do we still need this TODO?

[lemunozm]

Not for this PR, it comes from a cherry-pick from #1605

Good eye!

[lemunozm]

Actually, just realising that I skipped to double-check this pallet crate because it was under gateway and it still contains paths.

[lemunozm]

But they're local so not big issue
