Instead of polyfilling it with vm.SourceTextModule,
use a built-in source text module loader so that we can
also build the code cache for it at build tiem to
embed the code cache for them in the binary.
Drive-by: instead of inferring how to compile a particular
built-in at run time, do the inferring at build time,
so the function-based built-ins can be compiled using
parameters quickly looked up from a static map, and
the builtins that should be compiled as source text
modules are known internally based on extension in
the source code (at run time, the extensions are all
removed).

When the source text module is compiled without custom callbacks,
instead of calling into JS land from the per-isolate import.meta
initializer and then back to C++ land to set up lazy data
properties, just do the initialization all in C++ land.
Only import.meta.resolve initialization will call back
into JS land to generate a closure that call the cascaded loader
for resolution.
In addition, simplify the loader structure by merging
allowImportMetaResolve into isForAsyncLoaderHookWorker - the two
are essentially equivalent, as import.meta.resolve is only
allowed in a non-loader-hook worker thread's loader.

It should remove both the error and the ready event listeners
attached when either of them fires, instead of removing only
the one whose corresponding event fires, otherwise the other
event listener will always get leaked.

Previously, we ignored all indicators of the body (content-length or
transfer-encoding headers) and treated any information following
the headers as part of the upgraded stream. We now fully process the
requests bodies separately instead, allowing us to automatically handle
correct parsing of the body like any other HTTP request.
This is a breaking change if you are currently accepting HTTP Upgrade
requests with request bodies successfully, or if you use
socket-specific fields & methods on the upgraded stream argument.
In the former case, before now you will have received the request body
and then the upgraded data on the same stream without any distinction
or HTTP parsing applied. Now, you will need to separately read the
request body from the request (the 1st argument) and the upgraded
data from the upgrade stream (the 2nd argument). If you're not
interested in request bodies, you can continue to just read from the
upgrade stream directly.
In the latter case, if you want to access the raw socket, you should do
so via request.socket, instead of expecting the 2nd argument to be a
socket.

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.
