Fix runtime no-std/std builds, and other missing features

[teor2345]

PR #3411 removed default features that should have been included in some dependencies (but weren't included in every dependency). This PR restores those default features.

It also adds two extra jobs to PR CI, so this doesn't happen again:~~

• subspace-runtime snapshot build (covering the most important no_std build)
• check all crates individually (covering all possible missed features, including tokio/rt and test runtimes)

Code contributor checklist:

• I have read, understood and followed contributing guide

Which crate was brining the std that lead to runtime builds being failed ?

[vedhavyas]

technically not required if we can just clippy consensus runtime and domain runtimes with no-std

[teor2345]

That would only discover some issues. The runtimes all build with commit 94bff8b, but there are fixes to 10+ other crates that are only covered by this check (see the fix commits after that commit).

It only takes 2.5 minutes (edit: still working out how long it takes) to run these checks, so it seems worth doing them.

Before PR #3411, a significant number of crates had std features activated, but bug mainmatter/cargo-autoinherit#40 in the automated workspace dependency tool disabled those features.

This PR restores the previous std dependencies as they were before PR #3411.

If we want to enable/disable std in subspace-runtime, let’s do that in another PR?
Commit 94bff8b (and maybe earlier commits) are the ones to look at to make that change.

Edit: I also need to fix the CI cache keys to avoid conflicts.

Why do we need this to be duplicated in test deps and actual deps ?

[teor2345]

Because it is required by the tests, but optional for production code.

[teor2345]

I've resolved the conversations around CI by moving those commits to another PR, so that we can get this PR merged and the runtime snapshots built.

Would have preferred them in the same commit so that CI would run those actions as well rather merging this and that seperately.

I merged that branch into this PR, and updated the names and documentation based on your review in PR #3427.
