Attempt to split up CI build steps into separate jobs (FuelLabs#807)

* Attempt to split up CI build steps into separate jobs

Not sure if this will work just yet, but hoping this splits up the
`build` CI job to execute jobs in parallel, synchronising where
necessary using the `<job_id>.needs.<other_job_id>` feature.

Hopefully this cuts down on waiting time and makes the results a little
more readible from within the PRs.

Closes FuelLabs#772.

* Move `fuel-core` service into E2E test job

* Fix install-toolchain -> install-rust-toolchain

* Remove run-fuel-core job dep as no longer exists

* Fix publish job deps

* Checkout repo after Rust installation

* Inline checkout and rustup installation steps

* Make sure prev run cancelled first. Dont publish bad fmt.

* Try enabling cache for all jobs with Rust builds

* Move clippy check into main CI workflow

* Don't publish unless clippy passes. Make more consistent naming.
