Support parallel for `all?` command

[Kangaxx-0]

Description

Parallelism support for internal command all as requested from #6061

TODO - I will add parallelism support for other commands in different PRs

Tests

Make sure you've done the following:

• [ ] Add tests that cover your changes, either in the command examples, the crate/tests folder, or in the /tests folder.
• [ ] Try to think about corner cases and various ways how your changes could break. Cover them with tests.
• [ ] If adding tests is not possible, please document in the PR body a minimal example with steps on how to reproduce so one can verify your change works.

Make sure you've run and fixed any issues with these commands:

• [x] cargo fmt --all -- --check to check standard code formatting (cargo fmt --all applies these changes)
• [x] cargo clippy --workspace --features=extra -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect to check that you're using the standard code style
• [x] cargo test --workspace --features=extra to check that all the tests pass

I'm doing some refactor of the engine which might make this a bit harder. We may want to hold off on adding more parallel commands until we get a good idea of how it will change how parallel code works in the engine.

making this a draft considering jt's comments.

closing this in favor of waiting to see if it's experiments pan out.
