LibJS: Optimize Function.prototype.apply()

...by avoiding `CreateListFromArrayLike` in cases when we could directly
use elements of underlying object's indexed properties storage.

Makes this program go 2.1x faster:
```js
function target(a, b, c) {
    return a + b + c;
}

const args = [1, 2, 3];
let result = 0;

(function() {
    for (let i = 0; i < 10_000_000; i++) {
        result += target.apply(null, args);
    }
})();
```
