C/C++ DevTools Support (DWARF) - Debug C++ WebAssembly Apps

C/C++ DevTools Support (DWARF) is a useful Chrome Extension specifically designed for developers. It provides an adapter between a WebAssembly application running in a browser and Chrome DevTools, allowing you to debug C++ applications exported to WebAssembly directly. The extension works best with the latest Chrome Canary and Dev versions and requires valid DWARF information in your WebAssembly export.

I used this with the chromium snap. The snap confinement prevented it from loading the source files so I had to force the snap into `--devmode` with `snap refresh --devmode --beta chromium && snap refresh --devmode --stable chromium` to work around that. That's a bit of a security issue since it disabled both updates and confinement, so use with caution! Once done, I was able to do source level debugging (break points, single stepping, viewing variables etc) of Rust code just fine, even on stable chromium.
