This change allows all boolean flags to be negated using the `--no-`
prefix.
Flags that are `true` by default (for example `--deprecation`) are
still documented as negations.
With this change, it becomes possible to easily flip the default
value of a boolean flag and to override the value of a flag passed
in the NODE_OPTIONS environment variable.
`process.allowedNodeEnvironmentFlags` contains both the negated and
non-negated versions of boolean flags.

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.
