Revert of BackgroundGradientView: -drawBackground: → -drawRect: (patchset #2 id:40001 of https://codereview.chromium.org/2336453002/ )

Reason for revert:
AnimatableView inherits from BackgroundGradientView, so a number of
other views which *don't* want backgrounds end up inheriting from
BackgroundGradientView. This widened the scope of the change beyond what
I intended.

Original issue's description:
> BackgroundGradientView: -drawBackground: → -drawRect:
>
> BackgroundGradientView had a -drawBackground: method that its clients
> were expected to call. This change moves background drawing to
> -drawRect: so that the it happens by default.
>
> Subclasses that did custom drawing already override -drawRect:, but this
> removes a couple of overrides that just forwarded to -drawBackground:.
