Subject: fix: enable worker_threads

Electron sets NODE_USE_V8_PLATFORM to false, because Electron
initializes the v8 platform itself and Node.js worker thread
initialization relies on the platform it uses having been set inside
code guarded by NODE_USE_V8_PLATFORM.

This commit fixes this problem by changing node_worker to use the three-arg
implementation of `NewIsolate` to prevent it trying to use a possibly-null ptr.
