fix: strict type check for cross realms (#21669)
Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when
using `Object.prototype.isPrototypeOf` to check built-in types.
```js
import vm from "node:vm";
const err = new Error();
const crossErr = vm.runInNewContext(`new Error()`);
console.assert( !(crossErr instanceof Error) );
console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) );
```
This PR changes to check using internal slots solves them.

current:
```
> import vm from "node:vm";
undefined
> vm.runInNewContext(`new Error("message")`)
Error {}
> vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`)
Date {}
```
this PR:
```
> import vm from "node:vm";
undefined
> vm.runInNewContext(`new Error("message")`)
Error: message
at <anonymous>:1:1
> vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`)
