Revert 188637 "Added text line limits to collapsed and expanded ..."

It appears that r188637 is causing flakiness of ash_unittests on Win8 Aura:

http://build.chromium.org/p/chromium.win/builders/Win8%20Aura/builds/3400

> Added text line limits to collapsed and expanded notifications.
> 
> This is done through a new BoundedLabel views::Label subclass that
> supports a max_lines value. This class comes with unit tests covering
> its basic functionality.
> 
> Also, the Notifications Galore! test app was updated to include test
> notifications with long titles, long messages, and long items which can
> be used for manual tests of the line limits.
> 
> As with the rest of the collapse/expand functionality currently
> committed, this only applies to the notification center. Notification
> toasts are currently still always expanded and text line limits have not
> been tested for them.
> 
> There are some known issues with incorrect notification card sizes in
> the notification center after some sequence of create/destroy
> operations, and these will be addressed in a separate change list.
