Ensure duplicate commands with different exit codes show correct command decorations

[Tyriar]

This is a follow up from #143707 which worked around the majority case of an issue.

See the workaround: 78a9a54

The proper fix will involve sending both the exit code and the history ID over to VS Code which will then do what's happening now but also have the correct exit code to set, instead of assuming it's the last command's exit code.

We should write a little script as part of this that alternates exit codes by setting/unsetting an environment variable so it's easier to test and verify.

The issue being worked around is actually caused by ignoredups or ignoreboth being included in $HISTCONTROL.

Good test case from #154343

python -c $'import random\nif (random.randint(0, 1000) % 2 == 0):\n raise NotImplementedError \n'

[Tyriar]

To verify:

1. Run some commands
2. Check Terminal: Run Recent Command, they should all show up in current session
3. Press ctrl+c in between some commands, including typing out a command and hitting ctrl+c to abandon it
4. Check Terminal: Run Recent Command, the lines with ctrl+c shouldn't show up
5. Run python -c $'import random\nif (random.randint(0, 1000) % 2 == 0):\n raise NotImplementedError \n' several times, failed and success should match whether the exception was thrown.
