Typed Events for forwardEvents

[TheHadiAhmadi]

We can use $$Events same as $$Props and support all native events (only if using forwardEvents).

<script lang="ts">
  ....
  type $$Events = NativeEvents & {
     changed: CustomEvent<string>
  };

</script>
<div use:forwardEvents ....>
  ....
</div>
