add $nu.data-dir for completions and $nu.cache-dir for other uses (#13122)
# Description

This PR is an attempt to add a standard location for people to put
completions in. I saw this topic come up again recently and IIRC we
decided to create a standard location. I used the dirs-next crate to
dictate where these locations are. I know some people won't like that
but at least this gets the ball rolling in a direction that has a
standard directory.

This is what the default NU_LIB_DIRS looks like now in the
default_env.nu. It should also be like this when starting nushell with
`nu -n`
```nushell
$env.NU_LIB_DIRS = [
    ($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
    ($nu.data-dir | path join 'completions') # default home for nushell completions
]
```

I also added these default folders to the `$nu` variable so now there is
`$nu.data-path` and `$nu.cache-path`.

While I was in there, I also decided to add a cache dir

### This is what the default looks like in Ubuntu.

### This is what it looks like with XDG_CACHE_HOME and XDG_DATA_HOME
overridden
```nushell
XDG_DATA_HOME=/tmp/data_home XDG_CACHE_HOME=/tmp/cache_home cargo r
```

### This is what the defaults look like in Windows (username scrubbed to
protect the innocent)

How my NU_LIB_DIRS is set in the images above
```nushell
$env.NU_LIB_DIRS = [
    ($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
    '/Users/fdncred/src/nu_scripts'
    ($nu.config-path | path dirname)
    ($nu.data-dir | path join 'completions') # default home for nushell completions
]
```

Let the debate begin.

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

# 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.
