This commit simplifies error serialization, relying on the advanced IPC for child processes & worker threads. Unnecessary code has been removed. Possibly breaking changes: * Renamed and removed fields from the undocumented AssertionError class, including the raw values * Changes to the undocumented TAP output; stack traces are a bit worse, the rest is about the same but some fields have different names or values * `nyc` stack frames are no longer ignored; we assume you're using the native code coverage tools
