Implement open button for restoring closed tabs from History page.

The new "Open" button lets users quickly restore multiple pages from
their history. Instead of right-clicking each item and restoring them one
by one, users can just check the pages they want and click "Open."
All selected pages will open at once in new tabs, making it much faster
to get back to where they left off.
