MD History: Use iron-a11y-announcer to announce search result messages

The existing method we were using, `announceAccessibleMethod`, did
not correctly announce messages on Canary, possibly due to timing
issues. iron-a11y-announcer appears to be more robust for making
sure messages are actually announced, since they do not immediately
disappear from the DOM tree.

michaelpg@, can you please take a look?

All of the other MD History folks are OOO, and this fix is needed for our
accessibility review (see crbug.com/606527 for context).
