Use workspace dependencies more.

[waywardmonkeys]

Description
In the past, workspace dependencies couldn't be used everywhere due to complications in the Firefox environment. These are believed to be resolved and so we can try using them again to reduce version management overhead and duplicated information.

This patch makes some dependencies into workspace dependencies.

The bitflags dependency is changed to version 2.6 to match what was in naga rather than the bare 2 used elsewhere.

Testing
Compilation.

Checklist

• Run cargo fmt.
• Run cargo clippy. If applicable, add:
  • --target wasm32-unknown-unknown

• Run cargo xtask test to run tests.
• Add change to CHANGELOG.md. See simple instructions inside file. EDIT by @ErichDonGubler: Not necessary. 🙂

This could be a draft and get updated as more dependencies are switched over, or we could use this to be sure that there aren't issues from enabling this.

I'm going to merge this in a few hours, unless somebody has an objection (CC @gfx-rs/wgpu); I think the potential for conflicts is high, and I haven't felt or seen any controversy that what's here already is fine by itself.

[waywardmonkeys]

I've rebased this forward, added in the further work that I'd done.

Should this close #3407? I think so. I don't think we want all the deps in the workspace toml, only the ones present in more than one crate.

To me it seems like tracking all versions in one coherent place is nice. That way you also don't have to be aware of this and go move dependencies back and forth when they start being used in >1 place, or have their use removed and end up remaining used by just one crate.

That's fair, let's keep it open for the time being then.

Just waiting on @gfx-rs/naga's approval here.
