widget/material: [API] add description argument to IconButton

Browse Source 
Icons have no inherent semantic meaning such as a label, so this change
adds another argument to the IconButton constructor for the client to
provide a description.

This is an API change, because it seems best to force every client to
provide semantic descriptions for icon buttons.
