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")`)
2018-12-10T02:26:59.002Z
```
