TabbedPane: Some specs changes for highlight vertical mode

This cl changes several specs of TabbedPane in highlight vertical mode:
1. Max row length should be capped at 192, with right padding of 8px.
For long text, truncate with ellipsis.
2. Change active color from #4285F4 to #1A73E8.
3. Do not show MdTab border when focusing in highlighted mode. Instead
hightlighing with darker blue.
