Previously the native ShadowRealm objects were never actually tracked in the heap snapshot - the tracking starts with the Environment, we don't call the tracking methods unless it's reachable natively from the Environment. This patch adds a set in the Environment for tracking shadow realms in the heap snapshot. Drive-by: remove redundant MemoryInfo() overrides from the derived classes of Realm and remove the tracking of `env` from `Realm::MemoryInfo()` because the realms don't hold the Environment alive (even for the principal realm, it's the other way around).

Can we add a test case like https://github.com/nodejs/node/blob/main/test/pummel/test-heapdump-zlib.js? |
