Aliaksandr Kalenik 93cd17db74 LibJS: Add fast path internal_has_property() for Array 
If array has packed index property storage without holes, we could check
if indexed property is present simple by checking if it's less than
array's length.

Makes the following program go 1.1x faster:
```js
function f() {
    let array = [];
    for (let i = 0; i < 3_000; i++) {
        array.push(i);
    }

    for (let i = 0; i < 10_000; i++) {
        array.map(x => x * 2);
    }
}

f();
```
