bootstrap: use different scripts to setup different configurations
This patch splits the handling of `isMainThread` and `ownsProcessState` from conditionals in `lib/internal/bootstrap/node.js` into different scripts under `lib/internal/bootstrap/switches/`, and call them accordingly from C++ after `node.js` is run. This: - Creates a common denominator of the main thread and the worker thread bootstrap that can be snapshotted and shared by both. - Makes it possible to override the configurations on-the-fly.
