Spanned Value step 1: span all value cases (#10042)
# Description

This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.

We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

# 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 -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` 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
> ```

nu-cmd-extra

the extra commands are not part of the Nushell binary

The commands in this crate are the extra commands of Nushell. They do not get built for the release and it is the responsibility of the developer to build these commands if they want to use them.

These commands are not going to part of the 1.0 Api; meaning that there is no guarantee longer term that these commands will be around into the future. Of course since they are part of the source tree one could always incorporate them into their own custom release.

How to build the commands in this crate

Step 1 is to read the installation notes for Nushell which is located in our Nushell book.

Once Rust is installed you can then build Nushell with the following command.

cargo build --features=extra

Your Nushell binary which just got built is called nu and will be located here.
