Cherry-pick with modification: cc: PictureLayerImpl with empty bounds should not have tiles

Cherry-pick of Chromium crrev.com/r230368.

Removed changes to add new test to avoid gyp/mk churn.

BUG: 11288267

Original description:

If a PictureLayer bounds is set to from non-empty to empty,
PictureLayer::Update is skipped so the picture pile is not
updated. In this case, the PictureLayerImpl should not have
tilings.
