ESM resolution and loading is now always synchronous from a
non-loader-hook thread. If no asynchrnous loader hooks are
registered, the resolution/loading is entirely synchronous.
If asynchronous loader hooks are registered, these would be
synchronous on the non-loader-hook thread, and asynchronous
on the loader hook thread.
This avoids several races caused by async/sync loading sharing
the same cache. In particular, asynchronous loader hooks
now works with `require(esm)` - previously it tends to break
due to races.
In addition, when an asynchronous loader hook
returns a promise that never settles, the main thread no longer
silently exits with exit code 13, leaving the code below
any module loading calls silently ignored without being executed.
Instead, it now throws ERR_ASYNC_LOADER_REQUEST_NEVER_SETTLED
which can be caught and handled by the main thread. If the module
request comes from `import()`, the never-settling promise is
now relayed to the result returned by `import()`.
Drive-by: when annotating the error about importing undetectable
named exports from CommonJS, it now no longer reload the source
code of the CommonJS module, and instead reuses format information
cached when the module was loaded for linking.

Previously, formatExtraProperties applied ctx.stylize to the entire
'[key]: value' string. This caused the colon and space to be styled,
making the output inconsistent with normal object properties.
Now, only the key itself is stylized, and the colon and space remain
unstyled, aligning with the formatting of regular properties.

Previously the addAfterUserSerailizeCallback() wasn't
ready to be used for building the built-in snapshot.
This patch initializes the callbacks at the time
lib/internal/v8/start_snapshot.js is loaded, so that
these callbacks get run correctly when building the
built-in snapshot.
Currently when building the built-in snapshot,
addAfterUserSerializeCallback() is only used by createUnsafeBuffer(),
other usages can only come from user-land snapshots,
which is covered by tests, but what gets run by the
built-in snapshot building process is less visible, and the
path used by createUnsafeBuffer() isn't reliably visible in user
land either. This adds an internal usage counter in debug builds
to verify this path when building the built-in snapshot.

- This updates the comments that assume loader hooks must be async
- Differentiate the sync/async loader hook paths in naming
`#customizations` is now `#asyncLoaderHooks` to make it clear
it's from the async APIs.
- Differentiate the paths running on the loader hook thread
(affects the loading of async other loader hooks and are async)
v.s. paths on the main thread calling out to code on the loader
hook thread (do not handle loading of other async loader hooks, and
can be sync by blocking).
- `Hooks` is now `AsyncLoaderHooksOnLoaderHookWorker`
- `CustomizedModuleLoader` is now
`AsyncLoaderHooksProxiedToLoaderHookWorker` and moved into
`lib/internal/modules/esm/hooks.js` as it implements the same
interface as `AsyncLoaderHooksOnLoaderHookWorker`
- `HooksProxy` is now `AsyncLoaderHookWorker`
- Adjust the JSDoc accordingly
- Clarify the "loader worker" as the "async loader hook worker"
i.e. when there's no _async_ loader hook registered, there won't
be this worker, to avoid the misconception that this worker
is spawned unconditionally.
- The code run on the loader hook worker to process
`--experimental-loader` is moved into
`lib/internal/modules/esm/worker.js` for clarity.
- The initialization configuration `forceDefaultLoader` is split
into `shouldSpawnLoaderHookWorker` and `shouldPreloadModules`
as those can be separate.
- `--experimental-vm-modules` is now processed during pre-execution
and no longer part of the initialization of the built-in ESM
loader, as it only exposes the vm APIs of ESM, and is unrelated
to built-in ESM loading.

Implements the WHATWG DOM specification for passive event listeners,
ensuring that calls to `preventDefault()` are correctly ignored within
a passive listener context.
An internal `kInPassiveListener` state is added to the Event object
to track when a passive listener is executing. The `preventDefault()`
method and the `returnValue` setter are modified to check this state,
as well as the event's `cancelable` property. This state is reliably
cleaned up within a `finally` block to prevent state pollution in
case a listener throws an error.
This resolves previously failing Web Platform Tests (WPT) in
`AddEventListenerOptions-passive.any.js`.
