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.

Otherwise Node.js will try to read data from the handle.
This causes issues when Node.js is already reading from the
same handle, but a different associated stream
(e.g. a possible IPC channel).

Adds destroy() and _destroy() methods to Readable, Writable, Duplex
and Transform. It also standardizes the behavior and the implementation
of destroy(), which has been inconsistent in userland and core.
This PR also updates all the subsystems of core to use the new
destroy().
