Move all crate dependencies to the workspace Cargo.toml (#6179)

[alfiedotwtf]

Description

For #6179, PR #6501 kept bumping into errors as it was doing too many things, so I've split that PR into multiple PRs. This is the first, and the only thing it does is move all of the various Cargo.toml dependencies into the single workspace Cargo.toml.

Future PRs will:

• Update dependency versions
• Update code that breaks from the version bumps

Checklist

• I have linked to any relevant issues.
• I have commented my code, particularly in hard-to-understand areas.
• I have updated the documentation where relevant (API docs, the reference, and the Sway book).
  • If my change requires substantial documentation changes, I have requested support from the DevRel team
• I have added tests that prove my fix is effective or that my feature works.
• I have added (or requested a maintainer to add) the necessary Breaking* or New Feature labels where relevant.
• I have done my best to ensure that my PR adheres to the Fuel Labs Code Review Standards.
• I have requested a review from the relevant team or maintainers.
