We allow the C part to discover weak fields during tracing so that we will clear or forward them during the weak reference processing phase.
The `ruby` repo is merged with `master` on 2025-08-25. The upstream is now using `rb_gc_mark_weak` for more fields. In response to that, we properly implemented the handling of weak fields when using MMTk. However, we are now temporarily treating WeakMap as a strong map because it needs to be rehashed during the weak reference processing phase. We also added eBPF probes for weak fields.
