- Use a Map instead of an Object for signal wraps since it is used

This patch splits the execution mode selection from the environment
setup in `lib/internal/bootstrap/node.js`, and split the entry point
of different execution mode into main scripts under
`lib/internal/main`:
- `check_syntax.js`: used when `-c`/`--check` which only checks the
syntax of the input instead of executing it.
- `eval_stdin.js`: used when `-e` is passed without value and stdin
is not a TTY (e.g. something is piped).
- `eval_string`: used when `-e` is passed along with a string argument
- `inspect.js`: for `node inspect`/`node debug`
- `print_bash_completion.js`: for `--completion-bash`
- `print_help.js`: for `--help`
- `prof_process.js`: for `--prof-process`
- `repl.js`: for the REPL
- `run_main_module.js`: used when a main module is passed
- `run_third_party_main.js`: for the legacy `_third_party_main.js`
support
- `worker_thread.js`: for workers
This makes the entry points easier to navigate and paves the way
for customized v8 snapshots (that do not need to deserialize
execution mode setup) and better embedder APIs.
As an example, after this patch, for the most common case where
Node.js executes a user module as an entry point, it essentially
goes through:
- `lib/internal/per_context.js` to setup the v8 Context (which is
also run when setting up contexts for the `vm` module)
- `lib/internal/bootstrap/loaders.js` to set up internal binding
and builtin module loaders (that are separate from the loaders
accessible in the user land).
- `lib/internal/bootstrap/node.js`: to set up the rest of the
environment, including various globals and the process object
- `lib/internal/main/run_main_module.js`: which is selected from
C++ to prepare execution of the user module.
This patch also removes `NativeModuleLoader::CompileAndCall` and
exposes `NativeModuleLoader::LookupAndCompile` directly so that
we can handle syntax errors and runtime errors of bootstrap
scripts differently.

2. The requirement of explicitly adding the dependency to node-report

Major deviation from the module version of the node-report is that the
report is generated in JSON format, as opposed to human readable text.

In addition, store the JSON string separately in NativeModuleLoader,

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.

Allow reading from stdio streams that are conventionally
associated with process output, since this is only convention.
This involves disabling the oddness around closing stdio
streams. Its purpose is to prevent the file descriptors
0 through 2 from being closed, since doing so can lead
to information leaks when new file descriptors are being
opened; instead, not doing anything seems like a more

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.

that accepts an options object. The options object may include
a new `detail` option that allows additional detail text to be
associated with the warning. By default, this additional text
will be printed to stderr along with the warning, and included
on the Warning Error object using the `.detail` property.
e.g.
```js
process.emitWarning('A message', {
code: 'WARNING123',
detail: 'This is additional detail'
});
// Emits:
// (node {pid}) [WARNING123] Warning: A message
// This is additional detail
```

The unhandled promise rejection warning uses a template literal and
prints the reason a promise was rejected. If rejecting with a symbol,
the symbol failed to convert to a string and the process crashed. Now,
symbols are casted to strings and the process does not crash.

The --redirect-warnings command line argument allows process warnings
to be written to a specified file rather than printed to stderr.
Also adds an equivalent NODE_REDIRECT_WARNINGS environment variable.
If the specified file cannot be opened or written to for any reason,
the argument is ignored and the warning is printed to stderr.
If the file already exists, it will be appended to.

Give better stack traces for `PromiseRejectionHandledWarning`
and `UnhandledPromiseRejectionWarning`s.
For `PromiseRejectionHandledWarning`, when it is likely that there
is an `Error` object generated, it is created early to provide a
proper stack trace.
For `UnhandledPromiseRejectionWarning`, the stack trace of the
underlying error object is used, if possible.

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.
