Move worker bootstrap code into worker_thread_only.js from
internal/worker.js since they are only run once during bootstrap.

- Move `setupProcessStdio` which contains write access to
the process object into `bootstrap/node.js`
- Move `MessagePort`, `MessageChannel`, `ReadableWorkerStdio`,
and `WritableWorkerStdio` into `internal/worker/io.js`
- Move more worker-specific bootstrap code into
`internal/process/worker_thread_only` from `setupChild`
in `internal/worker.js`, and move the `process._fatalException`
overwrite into `bootstrap/node.js` for clarity.

This patch split part of the bootstrappers into three files:
- `lib/internal/process/main_thread_only.js`: contains bootstrappers
that can only be run in the main thread, including
- `setupStdio` for the main thread that sets up `process.stdin`,
`process.stdout`, `process.error` that may interact with external
resources, e.g. TTY/File/Pipe/TCP sockets
- `setupProcessMethods` that setup methods changing process-global
states, e.g. `process.chdir`, `process.umask`, `process.setuid`
- `setupSignalHandlers`
- `setupChildProcessIpcChannel` that setup `process.send` for
child processes.
- `lib/internal/process/worker_thread_only.js`: contains bootstrappers
that can only be run in the worker threads, including
- `setupStdio` for the worker thread that are streams to be
manipulated or piped to the parent thread
- `lib/internal/process/per_thread.js`: contains bootstrappers
that can be run in all threads, including:
- `setupAssert` for `process.assert`
- `setupCpuUsage` for `process.cpuUsage`
- `setupHrtime` for `process.hrtime` and `process.hrtime.bigint`
- `setupMemoryUsage` for `process.memoryUsage`
- `setupConfig` for `process.config`
- `setupKillAndExit` for `process.kill` and `process.exit`
- `setupRawDebug` for `process._rawDebug`
- `setupUncaughtExceptionCapture` for
`process.setUncaughtExceptionCaptureCallback` and
`process.hasUncaughtExceptionCaptureCallback`
Hopefully in the future we can sort more bootstrappers in
`boostrap/node.js` into these three files and further group
them into functions that can be run before creating the
snapshot / after loading the snapshot.
This patch also moves most of the `isMainThread` conditionals
into the main bootstrapper instead of letting them scattered around
special-casing different implementations.
