Revert introduction of [workspace.dependencies].

[nnethercote]

This was done in #145740 and #145947. It is causing problems for people using r-a on anything that uses the rustc-dev rustup package, e.g. Miri, clippy.

This repository has lots of submodules and subtrees and various different projects are carved out of pieces of it. It seems like [workspace.dependencies] will just be more trouble than it's worth.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
