Files in `node_modules` are not authored by the user directly and the
original sources are less relevant to the user.
Skipping source maps in `node_modules` improves the general
performance. Add `module.setSourceMapsSupport(enabled, options)` to
skip source maps in `node_modules` if it is needed. This moves
all source maps related API to `node:module` and this a step to
promote the source maps API to stable.

This PR adds a |preload| arg to the node::LoadEnvironment to allow
embedders to set a preload function for the environment, which will run
after the environment is loaded and before the main script runs.
This is similiar to the --require CLI option, but runs a C++ function,
and can only be set by embedders.
The preload function can be used by embedders to inject scripts before
running the main script, for example:
1. In Electron it is used to initialize the ASAR virtual filesystem,
inject custom process properties, etc.
2. In VS Code it can be used to reset the module search paths for
extensions.

Previously we only had an internal assertion to ensure certain
code is executed before any user-provided CJS is run. This patch
adds another assertion for ESM.
Note that this internal state is not updated during source text
module execution via vm because to run any code via vm, some
user JS code must have already been executed anyway.
In addition this patch moves the states into internal/modules/helpers
to avoid circular dependencies. Also moves toggling the states to
true *right before* user code execution instead of after in case
we are half-way in the execution when internals try to check them.

This patch adds support for using
`vm.constants.USE_MAIN_CONTEXT_DEFAULT_LOADER` as
`importModuleDynamically` in all APIs that take the option
except `vm.SourceTextModule`. This allows users to have a shortcut
to support dynamic import() in the compiled code without missing
the compilation cache if they don't need customization of the
loading process. We emit an experimental warning when the
`import()` is actually handled by the default loader through
this option instead of requiring `--experimental-vm-modules`.
In addition this refactors the documentation for
`importModuleDynamically` and adds a dedicated section for it
with examples.
`vm.SourceTextModule` is not supported in this patch because
it needs additional refactoring to handle `initializeImportMeta`,
which can be done in a follow-up.

Follows @giltayar's proposed API:
> `register` can pass any data it wants to the loader, which will be
passed to the exported `initialize` function of the loader.
Additionally, if the user of `register` wants to communicate with the
loader, it can just create a `MessageChannel` and pass the port to the
loader as data.
The `register` API is now:
```ts
interface Options {
parentUrl?: string;
data?: any;
transferList?: any[];
}
function register(loader: string, parentUrl?: string): any;
function register(loader: string, options?: Options): any;
```
This API is backwards compatible with the old one (new arguments are
optional and at the end) and allows for passing data into the new
`initialize` hook. If this hook returns data it is passed back to
`register`:
```ts
function initialize(data: any): Promise<any>;
```
**NOTE**: Currently there is no mechanism for a loader to exchange
ownership of something back to the caller.

Previously we cache the time origin for the milestones in the user
land, and refresh it at pre-execution. As result the time origin
gets serialized into the snapshot and is therefore not deterministic.
Now we store it in the milestone array as an internal value and
reset the milestones at serialization time instead of
deserialization time. This improves the determinism of the snapshot.
Drive-by: remove the unused MarkMilestone() binding.

This patch adds snapshot support to single executable applications.
To build a snapshot from the main script when preparing the
blob that will be injected into the single executable application,
add `"useSnapshot": true` to the configuration passed to
`--experimental-sea-config`. For example:
```
{
"main": "snapshot.js",
"output": "sea-prep.blob",
"useSnapshot": true
}
```
The main script used to build the snapshot must invoke
`v8.startupSnapshot.setDeserializeMainFunction()` to configure the
entry point. The generated startup snapshot would be part of the
preparation blob and get injected into the final executable.
When the single executable application is launched, instead of running
the `main` script from scratch, Node.js would instead deserialize the
snapshot to get to the state initialized during build-time directly.
