Woah. I think I was able to make some progress on this !

I managed to compile WAMR’s interpreter/debug runtime with Emscripten and run it alongside `liblldb` inside the same browser process. LLDB now talks to WAMR’s GDB-remote stub through an in-memory RSP connection, so in WasmBolt I can load a DWARF-enabled Wasm program and do all the good stuff (breakpoints, next , continue etc) without a native debugger or a remote server completely in the browser 😃 

Offcourse an early prototype but here's a demo anyways

All the work on `ProcessWasm` gave me the LLDB-side foundation to make this experiment possible. Thanks for that ;)
