BHV-16056: Suppress tap event when moon.Item is disabled.

### Issue
Disabled `moon.Item` controls still generate tap events.

### Fix
We suppress tap events when disabled. Additionally, we had been explicitly suppressing tap events for the `headerWrapper` in `moon.ExpandableListItem` and its derivatives, and because this control is a `moon.Item` kind, we remove this explicit suppression.
