Ben Hillis 8496b4051c Add /attachdebugger option to automatically launch WinDbgX for test debugging (#40116)
* Add /attachdebugger option to automatically launch WinDbgX for test debugging

When /attachdebugger is passed to test.bat, run-tests.ps1 now:
- Starts te.exe with /waitfordebugger in the background
- Polls for the TE.ProcessHost.exe child process via WMI
- Launches WinDbgX attached directly to the test host PID
- With /inproc, attaches to TE.exe itself instead

This replaces the manual workflow of running /waitfordebugger, reading
the PID from the output, and launching WinDbgX separately.

* run-tests: use /inproc with /attachdebugger, simplify exit

Per review feedback from @OneBlue:
- Add /inproc when /attachdebugger is set so WinDbgX attaches
  directly to TE.exe instead of polling for TE.ProcessHost.exe
- Simplify exit to pass through TE.exe exit code directly

* docs: update /attachdebugger to reflect /inproc behavior

The script now always adds /inproc, so update the README to match:
WinDbgX attaches directly to TE.exe, no ProcessHost polling.

About

Windows Subsystem for Linux (WSL) is a powerful way for you to run your Linux command-line tools, utilities and applications, all unmodified and directly on Windows without the overhead of a traditional virtual machine or dual boot setup.

You can install WSL right away by running this command inside of your Windows command line:

wsl --install

You can learn more about best practices for setup, overviews of WSL and more at our WSL documentation page.

WSL also has related open source repositories:
