2bdcdfc3cb vm: rename vm.Module to vm.SourceTextModule
At the last TC39 meeting, a new type of Module Records backed by
JavaScript source called Dynamic Module Records was discussed, and
it is now at Stage 1. Regardless of whether that proposal makes it
all the way into the spec, SourceTextModule is indeed a more
descriptive and accurate name for what this class represents.

49681e7414 process: refactor emitWarning
Remove a couple of obsolete checks by refactoring the code with else.
Also remove the possibility of an undefined warning. That is neither
documented nor does it result in a usable warning.

cb261c8648 process: avoid using the same fd for ipc and stdio
There is already a check in place to prevent stdin and the IPC
channel from sharing a file descriptor. This commit adds a
similar check to stdout and stderr.

e43d91cdc1 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.

ddefa0f2c5 worker: enable stdio
Provide `stdin`, `stdout` and `stderr` options for the `Worker`
constructor, and make these available to the worker thread
under their usual names.

The default for `stdin` is an empty stream, the default for
`stdout` and `stderr` is redirecting to the parent thread’s
corresponding stdio streams.

cf72301545 lib: unmask mode_t values with 0o777
This commit allows permission bits higher than 0o777 to go through
the API (e.g. `S_ISVTX`=`0o1000`, `S_ISGID`=`0o2000`,
`S_ISUID`=`0o4000`).

Also documents that these bits are not exposed through `fs.constants`
and their behaviors are platform-specific, so the users need to
use them on their own risk.

2a9eb316a1 src: move internal loaders out of bootstrap_node.js
- Moves the creation of `process.binding()`, `process._linkedBinding()`
  `internalBinding()` and `NativeModule` into a separate file
  `lib/internal/bootstrap_loaders.js`, and documents them there.
  This file will be compiled and run before `bootstrap_node.js`, which
  means we now bootstrap the internal module & binding system before
  actually bootstrapping Node.js.
- Rename the special ID that can be used to require `NativeModule`
  as `internal/bootstrap_loaders` since it is setup there. Also put
  `internalBinding` in the object exported by `NativeModule.require`
  instead of putting it inside the `NativeModule.wrapper`
- Use the original `getBinding()` to get the source code of native
  modules instead of getting it from `process.binding('native')`
  so that users cannot fake native modules by modifying the binding
  object.
- Names the bootstrapping functions so their names show up
  in the stack trace.

e9ac80bb39 async_hooks: clean up usage in internal code
Instead of exposing internals of async_hooks & async_wrap throughout
the code base, create necessary helper methods within the internal
async_hooks that allows easy usage by Node.js internals. This stops
every single internal user of async_hooks from importing a ton of
functions, constants and internal Aliased Buffers from C++ async_wrap.

Adds functions initHooksExist, afterHooksExist, and destroyHooksExist
to determine whether the related emit methods need to be triggered.

Adds clearDefaultTriggerAsyncId and clearAsyncIdStack on the JS side
as an alternative to always calling C++.

Moves async_id_symbol and trigger_async_id_symbol to internal
async_hooks as they are never used in C++.

Renames newUid to newAsyncId for added clarity of its purpose.

Adjusts usage throughout the codebase, as well as in a couple of tests.

d62566e1b1 promises: refactor rejection handling
Remove the unnecessary microTasksTickObject for scheduling microtasks
and instead use TickInfo to keep track of whether promise rejections
exist that need to be emitted. Consequently allow the microtasks to
execute on average fewer times, in more predictable manner than
previously.

Simplify unhandled & handled rejection tracking to do more in C++ to
avoid needing to expose additional info in JS.

When new unhandledRejections are emitted within an unhandledRejection
handler, allow the event loop to proceed first instead. This means
that if the end-user code handles all promise rejections on nextTick,
rejections within unhandledRejection now won't spiral into an infinite
loop.

4444b6b9ad process: refactor nextTick for clarity
Do not share unnecessary information about nextTick state
between JS & C++, instead only track whether a nextTick
is scheduled or not.

Turn nextTickQueue into an Object instead of a class
since multiple instances are never created.

Other assorted refinements and refactoring.

b1acba363d process: slight refinements to nextTick
Remove length prop on NextTickQueue class. We technically don't need to
keep track of the length of the queue in two places as we already have
tickInfo doing that work (between the index & the length we have enough
data for everything).

Store asyncId in a const within the _tickCallback function. Accessing
Symbol properties seems to be quite a bit more expensive than string
keys so this actually has a decent performance impact.
