Make on:wheel event available in the <Input /> component

[walker-tx]

Describe the feature

I'm making an editable table, and I found it annoying that the default behavior for HTML elements is to scroll when the mouse hovers over them, if the input value is longer than the width of the element itself. The accepted way to handle this is through the elements wheel event:

<script>
  function handleWheel(event) {
    if (document.activeElement !== event.target) {
      event.preventDefault();
    }
  }
</script>

<input type="text" on:wheel={handleWheel}>

The current implementation doesn't make this handler available. Is it cool if I make a PR for this? I have it working in my repo, just wanna share the love 🙃

Will gladly accept a PR to forward this event up 😃
