make save stream on list stream data (#7675)
# Description

Closes: #7590

# User-Facing Changes

So the following command
```
1..100 | each { |i| sleep 400ms; $i} | save --raw -f output.txt
```

Will stream data to `output.txt`

But I'm note sure how to make a proper test for it, so I leave with no
new test cases..

Also rename from `string_binary_list_value_to_bytes ` to
`value_to_bytes` to accepts more Value type.

# 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` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# 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.
