From the pull request description

This adds a "zig" object to `heapStats` in `bun:jsc` that reports a counter for how many of what types are allocated for tracking in debug builds. It does this without allocating memory itself (allowing it to be threadsafe, without needing locks and without making debug builds meaningfully slower)…
