🐛 `crypto.randomBytes` errors for values above 65536

With the following worker and `nodejs_compat`, you'll receive an error:

```ts
import crypto from 'node:crypto';

export default {
async fetch(request, env, ctx): Promise {
const random = crypto.randomBytes(65537).toString('hex');
return new Response(random);
},
} satisfies ExportedHandler;
```

errors with ` QuotaExceededError: getRandomValues() only accepts buffers of size <= 64K but provided 65537 bytes.`.

VS in Node.js where this works fine:
```ts
import crypto from 'node:crypto';

const random = crypto.randomBytes(65537).toString('hex');
console.log(random);
```

I discovered this entirely by accident when passing the wrong variable to `randomBytes`, but figured it was worth reporting for Node.js compat conformance.
