perf(ext/fetch): use new instead of createBranded (#20624) 
This PR optimizes `fromInner*` methods of `Request` / `Header` /
`Response` used by `Deno.serve` and `fetch` by using `new` instead of
`ObjectCreate` from `createBranded`.

The "brand" is created by passing `webidl.brand` to the constructor
instead.


142449ecab/ext/webidl/00_webidl.js (L1001-L1005)

### Benchmark
```js
const createBranded = Symbol("create branded");
const brand = Symbol("brand");
class B {
  constructor(init) {
    if (init === createBranded) {
      this[brand] = brand;
    }
  }
}

Deno.bench("Object.create(protoype)", () => {
  Object.create(B.prototype);
});

Deno.bench("new Class", () => {
  new B(createBranded);
});
```
