Debugger improvements

[isc-bsaviano]

• Fix the automatic termination of REST and unit test debug sessions (issue reported to the WRC)
• Prevent VS Code from showing a Create File button for files that are deployed (issue reported to the WRC)
• Don't attempt to set a breakpoint that's from a file in a different workspace folder
• Fix debugging files in a client-side virtual workspace folder
• Explicitly report failure to set a breakpoint
• Use the document index to get determine the name of a document in a local file
• Cache the contents of files fetched during a debug session

LGTM, and I assume you'll get it tested by those who reported the issues it's intended to fix.

The customer has not verified this fix, but their setup was easy to replicate so I tested this myself. You can verify this yourself easily if you want. Just pull a 2025.1 community container, create a REST web app and dispatch class, then try to debug it. You'll see that it breaks in %SYS.cspServer instead of terminating automatically.

Happy to defer to your testing.

We were also experiencing this issue and I have pulled the beta build and it no longer pops up the create file which was our major issue in the WRC that we created.

Thanks for confirming @mloutraris!
