- Renamed `internal/process/write-coverage.js` to
`internal/coverage-gen/with_instrumentation.js`,
`internal/process/coverage.js` to
`internal/coverage-gen/with_profiler.js` to distinguish
the two better and added comments.
- Separate the coverage directory setup and the connection
setup, moves the directory setup into `node.js` and
closer to the exit hooks because that's where it's used.
- Moves the `process.reallyExit` overwrite and
`process.on('exit')` hooks setup into bootstrap/node.js
for clarity, and move them to a later stage of
bootstrap since they do not have to happen that early.

This patch:
- Moves `tryGetCwd`, `evalScript` and `fatalException` from
`bootstrap/node.js` into `process/execution.js` so that
they do have to be passed into the worker thread
setup function, instead the worker code can require them
when necessary.
- Moves `setUncaughtExceptionCaptureCallback` and
`hasUncaughtExceptionCaptureCallback` along with the two
global state `exceptionHandlerState` and
`shouldAbortOnUncaughtToggle` info `process.execution.js`
as those are only used by the fatalException and these
two accessors as one self-contained unit.

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.

Instead of treating config.gypi as a JavaScript file, specialize
the processing in js2c and make the serialized result a real JSON
string (with 'true' and 'false' converted to boolean values) so
we don't have to use a custom deserializer during bootstrap.
In addition, store the JSON string separately in NativeModuleLoader,
and keep it separate from the map of the builtin source code, so
we don't have to put it onto `NativeModule._source` and delete it
later, though we still preserve it in `process.binding('natives')`,
which we don't use anymore.
This patch also makes the map of builtin source code and the
config.gypi string available through side-effect-free getters
in C++.

This commit replaces a call to Number.isFinite() with a
cheaper typeof check. The subsequent range checks ensure that

Because most of its code (the getter) has nothing to do with
the actual bootstrapping and it is run per-thread.

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.
