LOG: [lldb-dap] Conditionally check UBSan stack trace on Darwin only (#178655)

non-darwin platforms may have incorrect stop information location
heuristics. Enable assertion once UBSan stopInfo heuristic is updated.

I hit this locally, I don't see it hitting any CI bot but should, Mostly
likely the CI linux bots may not have `compiler_rt` run time enabled.
