James M Snell a293ec7785 perf_hooks: restore GC tracking after snapshot deserialization

V8 GC callbacks do not survive a snapshot, so a `'gc'`
PerformanceObserver that was active while building a user-land
snapshot received no entries after deserialization, unless another
`'gc'` observer was created.

When `'gc'` is observed while building a snapshot, add a deserialize
callback that registers the GC callbacks again if `'gc'` observers are
still active.
