Unrolled build for #145740

Rollup merge of #145740 - nnethercote:workspace-members, r=Kobzol

Introduce a `[workspace.dependencies`] section in the top-level `Cargo.toml`

It lets us avoid a lot of repetition of crate versions, etc.

I've just done a few as a start. Many more can be done in follow-ups.

r? `@Kobzol`
