RuntimeEnabledFeatures::slimmingPaintOffsetCaching

RuntimeEnabledFeatures::slimmingPaintOffsetCaching

Put paint offset caching code under this condition because we may
enable it for slimming paint v1.

Also add a test for bug 533277, and exclude paint-offset workaround
when paint offset caching is enabled.

LGTM

Can we try unittesting these in the future? (Layouttest is fine for this patch)
