Improve crash call stack data.

[sean-mcmanus]

The previous crash call stack data was unnecessarily hard to analyze.

• Change "cpptools-srv2.txt" to "cpptools-srv2 process" so it's self-explanatory what it describes.
• Move address data that was consistent between crashes into the main crash call stack section and remove the inconsistent address data.

Fixed by Copilot with Claude Opus 4.8 in VS Code.

Pull request overview

This PR adjusts how C/C++ crash telemetry is generated in the extension to make crash call stack data easier to read and analyze by removing the separate “offset/address” telemetry field and restructuring the emitted crash header/details.

Changes:

• Removes the separate CrashingThreadCallStackOffsets telemetry property and simplifies the telemetry logging helpers.
• Changes the crash telemetry header/signal formatting (adds si_code/si_addr inline) and alters how address/offset data is appended to the call stack text.
• Updates the “C/C++ Crash Call Stacks” output formatting to include the new signal info.
