MD WebUI: Use dom-if to control hidden elements in <cr-toolbar>

This allows the <paper-spinner-lite> and the clear <paper-icon-button>
to not be stamped until they are needed. This results in a small
performance improvement (5-10ms on my Z620) across all pages which use
<cr-toolbar>. In particular, this is a 1-2% improvement in MD History.
