Update attribution on layer visibility changes

[mourner]

Closes #9824. Attribution is currently updated when the style changes (layers and sources added/removed, properties changed, etc.), but not updated when source visibility changes during zooming — either through going in or out of minzoom/maxzoom range, or through opacity change from zero to non-zero values or vice versa (e.g. through a zoom-based expression).

This PR introduces a new sourcedata event with sourceDataType: 'visibility', which the attribution control subsequently subscribes to for updating the attribution.
