`process.getBuiltinModule(id)` provides a way to load built-in modules
in a globally available function. ES Modules that need to support
other environments can use it to conditionally load a Node.js built-in
when it is run in Node.js, without having to deal with the resolution
error that can be thrown by `import` in a non-Node.js environment or
having to use dynamic `import()` which either turns the module into an
asynchronous module, or turns a synchronous API into an asynchronous
one.
```mjs
if (globalThis.process.getBuiltinModule) {
// Run in Node.js, use the Node.js fs module.
const fs = globalThis.process.getBuiltinModule('fs');
// If `require()` is needed to load user-modules, use
// createRequire()
const module = globalThis.process.getBuiltinModule('module');
const require = module.createRequire(import.meta.url);
const foo = require('foo');
}
```
If `id` specifies a built-in module available in the current Node.js
process, `process.getBuiltinModule(id)` method returns the
corresponding built-in module. If `id` does not correspond to any
built-in module, `undefined` is returned.
`process.getBuiltinModule(id)` accept built-in module IDs that are
recognized by `module.isBuiltin(id)`. Some built-in modules must be
loaded with the `node:` prefix.
The built-in modules returned by `process.getBuiltinModule(id)` are
always the original modules - that is, it's not affected by
`require.cache`.

We previously build the ESM facade (synthetic modules re-exporting
builtin's exports) for builtins even when they are not directly
import'ed (which rarely happens for internal builtins as that
requires --expose-internals). This patch removes
the eager generation to avoid the overhead and the extra
promises created in facade building when it's not reqested by the user.
When the facade is needed the ESM loader that can be requested

With this patch:
Users can now include assets by adding a key-path dictionary
to the configuration as the `assets` field. At build time, Node.js
would read the assets from the specified paths and bundle them into
the preparation blob. In the generated executable, users can retrieve
the assets using the `sea.getAsset()` and `sea.getAssetAsBlob()` API.
```json
{
"main": "/path/to/bundled/script.js",
"output": "/path/to/write/the/generated/blob.blob",
"assets": {
"a.jpg": "/path/to/a.jpg",
"b.txt": "/path/to/b.txt"
}
}
```
The single-executable application can access the assets as follows:
```cjs
const { getAsset } = require('node:sea');
// Returns a copy of the data in an ArrayBuffer
const image = getAsset('a.jpg');
// Returns a string decoded from the asset as UTF8.
const text = getAsset('b.txt', 'utf8');
// Returns a Blob containing the asset.
const blob = getAssetAsBlob('a.jpg');
```
Drive-by: update the documentation to include a section dedicated
to the injected main script and refer to it as "injected main
script" instead of "injected module" because it's a script, not
a module.

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.

This patch:
- Builds the set of modules that can be required by users with/without

`--expose-internals` but the default set is now in the snapshot. At
run time the CJS module loader only creates a frozen array out of it.
- `BuiltinModule.canBeRequiredWithoutScheme()` is now enough to
determine if an id can be required without `node:` without an
additional call to `BuiltinModule.canBeRequiredByUsers()`
- Replace the pending-to-deprecate methods on `Module` with an internal
implementation that only queries the CLI flags when being invoked.
So we can install these methods in the snapshot.
