Expose `preventScroll` on ElementReference.FocusAsync

Add an overload to ElementReference.FocusAsync that accepts preventScroll as an option:

public static ValueTask FocusAsync(this ElementReference elementReference, bool preventScroll);

---

I should probably add a new issue for this but I think FocusAsync() should also include preventScroll flag

Describe the bug

On Blazor server side, when you apply autofocus on your inputs the attribute is not being respected:

• At the first time, you can see the autofocus being applied but loses it after the page fully load
• When you use the navigation bar the autofocus is not applied at all

To Reproduce

Create a page with the followin code:

<input type="text" name="name" />

<input type="text" name="name1" autofocus />

Expected: If you don’t do anything while the page loads the autofocus must be aplied
