daae938 broke addons which create their own `Isolate` instances, because enabling the shared-readonly-heap feature of V8 requires all snapshots used for different `Isolate`s to be identical. Usage of addons that do this has probably decreased quite a bit since Worker threads were introduced in Node.js, but it’s still a valid use case, and in any case the breakage was probably not intentional (although the referenced commit did require test changes because of this issue). This commit addresses this issue partially by caching the V8 snapshot parameters and ignoring ones passed in from users in `NewIsolate()` when this feature is enabled, and makes the `NodeMainInstance` snapshot-based isolate creation also re-use this code.
