Revert of Cache gpu suitability in DisplayItemList, remove SetUnsuitable...ForTesting (patchset #7 id:120001 of https://codereview.chromium.org/1349913002/ )

Reason for revert:
Crashes :'( http://crbug.com/534810

Original issue's description:
> Cache gpu suitability in DisplayItemList, remove SetUnsuitable...ForTesting
>
> This patch moves the gpu suitability "cache" into display_item_list
> so that calls to DisplayItemList::IsSuitableForGpuRasterization are
> fast. With the cache moved we no longer need to track suitability in
> the recording source and can remove SetUnsuitableForGpuRasterizationForTesting.
