When V8 creates a context for snapshot building, it does not
install Error.stackTraceLimit. As a result, error.stack would
be undefined in the snapshot builder script unless users
explicitly initialize Error.stackTraceLimit, which may be
surprising.
This patch initializes Error.stackTraceLimit based on the
value of --stack-trace-limit to prevent the surprise. If
users have modified Error.stackTraceLimit in the builder
script, the modified value would be restored during
deserialization. Otherwise, the fixed up limit would be
deleted since V8 expects to find it unset and re-initialize
it during snapshot deserialization.

This commit introduces a new --experimental-test-isolation flag
that, when set to 'none', causes the test runner to execute all
tests in the same process. By default, this is the main test
runner process, but if watch mode is enabled, it spawns a separate
process that runs all of the tests.
The default value of the new flag is 'process', which uses the
existing behavior of running each test file in its own child
process.
It is worth noting that when the isolation mode is 'none', globals
and all other top level logic (such as top level before() and after()
hooks) is shared among all files.

Now that parseCommandLine() returns run() compatible arguments,
it makes sense to return setupTestReporters() as the setup()
argument to run(). This also removes another problematic use of
parseCommandLine() in setupTestReporters().

This commit consolidates all option parsing for the test runner
in the parseCommandLine() internal helper function. The exception
is a couple of temporary flags used for feature gating which
will eventually become no-ops. This consolidation is prep work
for supporting running test files in the test runner process.

This patch:
1. Refactor the routines used to compile and run an embedder
entrypoint. In JS land special handling for SEA is done
directly in main/embedding.js instead of clobbering the CJS
loader. Add warnings to remind users that currently the
require() in SEA bundled scripts only supports loading builtins.
2. Don't use the bundled SEA code cache when compiling CJS
loaded from disk, since in that case we are certainly not
compiling the code bundled into the SEA. Use a is_sea_main
flag in CompileFunctionForCJSLoader() (which replaces an unused
argument) to pass this into the C++ land - the code cache is
still read directly from C++ to avoid the overhead of
ArrayBuffer creation.
3. Move SEA loading code into
MaybeLoadSingleExecutableApplication() which calls
LoadEnvironment() with its own StartExecutionCallback().
This avoids more hidden switches in StartExecution() and
make them explicit. Also add some TODOs about how to support
ESM in embedded applications.
4. Add more comments

In this patch we split the serialization routine into two different
routines: `getCLIOptionsValues()` for only serializing the key-value
pairs and `getCLIOptionsInfo()` for getting additional information such
as help text etc. The former is used a lot more frequently than the
latter, which is only used for generating `--help` and building
`process.allowedNodeEnvironmentFlags`.
`getCLIOptionsValues()` also adds `--no-` entries for boolean options so
there is no need to special case in the JS land.
This patch also refactors the option serialization routines to
use v8::Object constructor that takes key-value pairs in one go
to avoid calling Map::Set or Object::Set repeatedly which can go
up to a patched prototype.

Split the `internal/process/esm_loader` file which contains the
singleton cascaded loader:
- The the singleton cascaded loader now directly resides in
`internal/modules/esm/loader`, where the constructor also lives.
This file is the root of most circular dependency of ESM code,
(because components of the loader need the singleton itself),
so this makes the dependency more obvious. Added comments about
loading it lazily to avoid circular dependency.
- The getter to the cascaded loader is also turned into a method
to make the side effect explicit.
- The sequence of `loadESM()` and `handleMainPromise` is now merged
together into `runEntryPointWithESMLoader()` in
`internal/modules/run_main` because this is intended to run entry
points with the ESM loader and not just any module.
- Documents how top-level await is handled.

Previously we wrapped the embedder entry point callback into a
binding and then invoke the binding from JS land which was a bit
convoluted. Now we just call it directly from C++.
The main scripts that needed to tail call the embedder callback now
return the arguments in an array so that the C++ land can extract
the arguments and pass them to the callback. We also set
`PauseOnNextJavascriptStatement()` for --inspect-brk and mark
the bootstrap complete milestone directly in C++ for these
execution modes.

This bootstraps ESM loaders in the ShadowRealm with
`ShadowRealm.prototype.importValue` as its entry point and enables
loading ESM and CJS modules in the ShadowRealm. The module is imported
without a parent URL and resolved with the current process's working

This test was flaky on Windows when trying to clean up the
tmp directory, probably because it relied on child processes
timing out and being killed.
This commit updates the test to check for debug output
from the test runner. This should be adequate because the
original change was effectively:
let concurrency = getOptionValue('--test-concurrency') || true;
The test runner now logs the value of the concurrency variable.
