Description of Changes

• Added a workspace Cargo.toml for Athena (otherwise the lints didn't work on me)

• Moved utils and some database mods from rbac-registration to shared crate

• Added a wrapper macro for wit-bindgen to share the bindings concisely

  • Notably, now configured to disable_custom_section_link_helpers: true.

• Refactored Athena src to use shared rather than wit-bindgen bindings, as well as shared utilities

• Fixed some of the clippy lints (e.g. added let _ = for some unused results). Maintaining the current behaviour.

Breaking Changes

Some rust mods and functions moved to shared.

Forgot to mention it here, for earthly to work I need path: "../../../wasi/wit", but for local dev I need path: "../../../../../wasm/wasi/wit"
