When using redirection, if a command generates non-zero exit code, the script should stop running (#11191)

Browse Source 
# Description
Fixes: #11153

To make sure scripts stop from running on non-zero exit code, we need to
invoke `might_consume_external_result` on
`PipelineData::ExternalStream`, so it can tell nushell if this command
exists with non-zero exit code.

And this pr also adjusts some test cases.

# User-Facing Changes
```nushell
^false out> /dev/null; print "ok"
```

After this pr, it shouldn't print ok.

# Tests + Formatting
Done
