fix exit_code handling when running a scripts with ctrlc (#11466) 
# Description
Fixes: #11394

When run `^sleep 3` we have an `exit_code ListStream`, and when we press
ctrl-c, this `ListStream` will return None. But it's not expected,
because `exit_code` sender in `run_external` always send an exit code
out.

This pr is trying to fix the issue by introducing a `first_guard` into
ListStream, it will always generate a value from underlying stream if
`first_guard` is true, so it's guarantee to have at least one value to
return.

And the pr also do a little refactor, which makes use of
`ListStream::from_stream` rather than construct it manually.

# User-Facing Changes
## Before
```
> nu -c "^sleep 3"  # press ctrl-c
> echo $env.LAST_EXIT_CODE
0
```

## After
```
> nu -c "^sleep 3"  # press ctrl-c
> echo $env.LAST_EXIT_CODE
255
```

# Tests + Formatting
None, sorry that I don't think it's easy to test the ctrlc behavior.

# After Submitting
None

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
