WIP physics tracing/recording

[Random-Scientist]

implements a tracing system that serializes all sable JNI commands to a file for playback by a minimal runner binary.
this opens up a lot of exciting possibilities for improving the physics engine down the line.

• integration testing and validation of changes
• ease of profiling/measuring performance changes on real recorded workloads
• repeatable benchmarks
• capturing PGO instrumentation data in CI builds
• faster iteration times to test physics changes
• reliable and controlled reproducers for physics bugs

At present there is a deadlock issue when recording with reentrant native calls. Also, this don't support (tracking the behavior of) external material collision handler callbacks yet.
