This implements a flavor of vm.createContext() and friends
that creates a context without contextifying its global object.
This is suitable when users want to freeze the context (impossible
when the global is contextified i.e. has interceptors installed)
or speed up the global access if they don't need the interceptor
behavior.
```js
const vm = require('node:vm');
const context = vm.createContext(vm.constants.DONT_CONTEXTIFY);
// In contexts with contextified global objects, this is false.
// In vanilla contexts this is true.
console.log(vm.runInContext('globalThis', context) === context);
// In contexts with contextified global objects, this would throw,
// but in vanilla contexts freezing the global object works.
vm.runInContext('Object.freeze(globalThis);', context);
// In contexts with contextified global objects, freezing throws
// and won't be effective. In vanilla contexts, freezing works
// and prevents scripts from accidentally leaking globals.
try {
vm.runInContext('globalThis.foo = 1; foo;', context);
} catch(e) {
console.log(e); // Uncaught ReferenceError: foo is not defined
}
console.log(context.Array); // [Function: Array]
```

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 fixes an error in parseYAML(text), the version sorting
coudn't be right as we compared an arrify string
(ie. a = ["v18.11, v16.7.0"]) with an array of strings
(ie. b = ["v18.07", "v16.7.0"]) in versionSort(a, b).
minVersion(a) couldn't find the minimum version with an arrify string
like a = ["v18.11, v16.7.0"].
That's why incorrect version history orders sometimes appeared.
Furthermore, no need to sort the added version as it always comes first.
So, it can be the last one to be pushed in the meta.changes array.

3. `defineReplaceableAttribute` should create IDL getter/setter.
4. Corrected `PerformanceResourceTiming` to inherit the public interface
`PerformanceEntry` instead of the internal interface
`InternalPerformanceResourceTiming`.
5. `detail` is not a specified attribute on `PerfomanceEntry`. Node.js
specific extensions are moved to a subclass of `PerformanceEntry` as
`PerformanceNodeEntry`.

This commit documents the event parameters and `http2stream.respond`,
and adds some tests to ensure the actual behaviors are aligned with
the docs.
Testing the 'Http2Server.sessionError' event is added by updating
`test/parallel/test-http2-options-max-headers-exceeds-nghttp2.js`.
The event seemingly has not been tested so far.
`ServerHttp2Session` is exported to validate the `session` event
and the `sessionError` event.
