fix: Remove symbolication that causes deadlocks

[github-actions]

Note

The pull request "fix: Remove symbolication that causes deadlocks" was created by @noahsmartin but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

Resolves #6560 (and all the other related issues)

This also has the benefit of unifying the debug and non-debug codepaths to reduce the chances that a bug affects one environment but not the other. For example, the debug behavior of buildStacktraceForCurrentThread would remove the frame for that function itself, but this wouldn't happen in non-debug (since it relied on symbolication). This PR preserves the non-debug behavior, now in all configurations
