optimized the copyError function by using ObjectAssign from primordials.
this change replaces the for-loop with ObjectAssign, which improves
memory usage and performance.
this change updates the copyError function in internal/assert.js to
use ObjectAssign for copying properties.

Prior pull request (#48726) hardened against prototype pollution
vulnerabilities but effectively missed some use-cases which
opened a window for prototype pollution for some child_process
functions such as spawn(), spawnSync(), and execFileSync().

This commit refactors the internals of snapshot tests to get the
name of the test file from the test context instead of passing
it to the SnapshotManager constructor. This is prep work for
supporting running test files in the test runner process.

This commit adds a filePath getter to the TestContext and
SuiteContext classes. This allows a context to be mapped back to
the original test file that created it, even if it was imported
from another file. This is useful for mapping features like test
snapshots to the correct test file. This is also prep work for
supporting running test files in the test runner process.

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.

Instead call the C++ code every time we need to check for a
trace category, now we get the C++ pointer to the flag that
holds the info if the trace is enabled and return this pointer
inside a buffer that we can use to call/check if the value is
enabled. With this change, no C++ call is made and the access
to the info happens in JS side, which has no perf penalty.

Snapshotted values are escaped after serialization.
This happens when serializing a value for comparison
when snapshots already exist, and also when updating them.
That is, snapshots are escaped in the internal storage,
but when written to disk, one "level" of escaping is removed.
That escaping is never added back when reading the snapshots back.
This makes even the simplest test trying to serialize a string
with an escape code in it fail, like the one I added here.

Tooling in the ecosystem have been using the __esModule property to
recognize transpiled ESM in consuming code. For example, a 'log'
package written in ESM:
export function log(val) { console.log(val); }
Can be transpiled as:
exports.__esModule = true;
exports.default = function log(val) { console.log(val); }
The consuming code may be written like this in ESM:
import log from 'log'
Which gets transpiled to:
const _mod = require('log');
const log = _mod.__esModule ? _mod.default : _mod;
So to allow transpiled consuming code to recognize require()'d real ESM
as ESM and pick up the default exports, we add a __esModule property by
building a source text module facade for any module that has a default
export and add .__esModule = true to the exports. We don't do this to
modules that don't have default exports to avoid the unnecessary
overhead. This maintains the enumerability of the re-exported names
and the live binding of the exports.
The source of the facade is defined as a constant per-isolate property
required_module_facade_source_string, which looks like this
export * from 'original';
export { default } from 'original';
export const __esModule = true;
And the 'original' module request is always resolved by
createRequiredModuleFacade() to wrap which is a ModuleWrap wrapping
over the original module.

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
