Add progress notification support to new-style notification.

CompactTitleMessageView is added to follow Android's behavior showing
notification title and message in single line when it has progress bar.
Also, added constructor option allow_round_corner to views::ProgressBar
so that progress bar style follows Material Design mock.

BUG= 726245 
TEST=manually tested by progress notification with
* short title, short message
* short title, long message
* long title, long message

Add percentage of progress in notification header.

Add percentage of progress in the header of new-style notification, so
that it would be consistent with the mock.

BUG= 726245 
TEST=manual, including environment with RTL language (Hebrew).
Android does not have this for progress bar at system level, so consistency wouldn't be a problem for this.
