Part of https://github.com/nushell/nushell/issues/12963, step 2.

This PR refactors changes the use of `expression.span` to
`expression.span_id` via a new helper `Expression::span()`. A new
`GetSpan` is added to abstract getting the span from both `EngineState`
and `StateWorkingSet`.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

`format pattern` loses the ability to use variables in the pattern,
e.g., `... | format pattern 'value of {$it.name} is {$it.value}'`. This
is because the command did a custom parse-eval cycle, creating spans
that are not merged into the main engine state. We could clone the
engine state, add Clone trait to StateDelta and merge the cloned delta
to the cloned state, but IMO there is not much value from having this
ability, since we have string interpolation nowadays: `... | $"value of
($in.name) is ($in.value)"`.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

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

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
