process: improve cwd performance
This caches the current working directory and only updates the variable
if `process.chdir()` is called.

lib: rename validateMode to parseMode
The function did not only validate the mode but it returns a new
value depending on the input. Thus `validate` did not seem to be an
appropriate name.

process: setup signal handler in prepareMainThreadExecution
Because this is only necessary in the main thread.
Also removes the rearming of signal events since no
signal event handlers should be created during the execution
of node.js now that we've made the creation of stdout and stderr
streams lazy - this has been demonstrated in the test coverage.

ec76f7cf8f lib: simplify 'umask'
Just check: if 'mask' is not undefined, just call 'validateMode' and
then return the unmask value, we don't need split them into two returns.

process: group main thread execution preparation code
This patch groups the preparation of main thread execution into
`prepareMainThreadExecution()` and removes the cluster IPC
setup in worker thread bootstrap since clusters do not use
worker threads for its implementation and it's unlikely to change.

lib: move signal event handling into bootstrap/node.js
Moves the `process.on()` and `promise.emit()` calls happened during
bootstrap for signal events into `bootstrap/node.js` so it's easier
to tell the side effects.

Drive-by changes:

- Moves the signal event re-arming to a point later during
  the bootstrap - as early as it were it's unlikely that there
  could be any existing signal events to re-arm for node-report.
- Use a Map instead of an Object for signal wraps since it is used
  as a deletable dictionary anyway.

process: split worker IO into internal/worker/io.js
- 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.

process: move child process IPC setup condition into node.js
Instead of branching in main_thread_only.js, move the branch on
process.env.NODE_CHANNEL_FD in node.js so it's easier to tell when
this needs to happen. Also added comments about what side effect
this causes, and lazy load `assert`.

src: move more process methods initialization in bootstrap/node.js
Instead of:

- Writing methods onto the process directly in C++ during
  `SetupProcessObject()` and overwrite with argument checks later
- Or, wrapping and writing them in `internal/process/*.js`

Do:

- Move the C++ implementations in node_process.cc and mark them static
  wherever possible
- Expose the C++ methods through a new
  `internalBinding('process_methods')`
- Wrap the methods in `internal/process/*.js` in a
  side-effect-free manner and return them back to
  `internal/bootstrap/node.js`
- Centralize the write to the process object based on conditions
  in `bootstrap/node.js`

So it's easier to see what methods are attached to the process object
during bootstrap under what condition and in what order.

The eventual goal is to figure out the dependency of process methods
and the write/read access to the process object during bootstrap, group
these access properly and remove the process properties that should not
be exposed to users this way.

Also correct the NODE_PERFORMANCE_MILESTONE_BOOTSTRAP_COMPLETE milestone
which should be marked before code execution.

process: move POSIX credential accessors into node_credentials.cc
Expose the POSIX credential accessors through
`internalBinding('credentials')` instead of setting them on the
process or bootstrapper object from C++ directly. Also moves
`SafeGetEnv` from `internalBinding('util')` to
`internalBinding('credentials')` since it's closely related to
the credentials.

In the JS land, instead of wrapping the bindings then writing
to the process object directly in main_thread_only.js, return
the wrapped functions back to bootstrap/node.js where they get
written to the process object conditionally for clarity.

25ad8decc6 lib: rearm pre-existing signal event registrations
process.on('somesignal', ...) semantics expect the process to catch the
signal and invoke the associated handler. `setupSignalHandlers` perform
the additional task of preparing the libuv signal handler and associate
it with the event handler. It is possible that by the time this is
setup there could be pre-existing registrations that pre-date this setup
in the boot sequence.

So rearm pre-existing signal event registrations to get upto speed.

process: split bootstrappers by threads that can run them
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.
