refactor(runtime): manual serialization of bootstrap data (#18448)
This commit changes how data required to bootstrap main and worker runtime is serialized. Instead of relying on serde_v8 and using JSON object, we're doing manual serialization to a "v8::Array". This limits number of V8 strings that need to be serialized by 16. It also made it clear that some data could be obtained during snapshotting instead of during bootstrap.
