Process tree missing from new WinDbg

[slightlyoff]

Per conversation with @aluhrs13, it appears that the Process Tree is missing from the new UI; only threads in the current process are visible. The old UI, which made it much easier to work in codebases like Chromium, was documented here:

While that's true and is something we might look into, I'll note that the UI is extensible (even via simple JavaScript).

In the interim, if having such a view helps... see the attached files here (they are renamed to have .txt so they'll attach to GitHub):

GalleryManifest.xml.txt
ProcessThreads.js.txt

You can:
- Make a directory (e.g.: ProcessThreads) in %LocalAppData%\DBG\UserExtensions
- Copy the files into that directory (removing the .txt extension)
- Restart the debugger

At that point, there should be a "Process & Threads" icon on the "Extensions" tab of the ribbon:

Clicking it will bring up a view similar in form to the old WinDbg one.... you can right click any process and/or thread in that view and "Switch To":

The JS stuff has long been documented... you can find documentation for the gallery manifesting at:

https://github.com/microsoft/WinDbg-Samples/blob/master/Manifest/README.MD

Hope that helps in the interim... The attached JS script should be easy to follow/edit to add whatever you want...
