Kartikaya Gupta 1ef110fd03 Bug 1405359 - Make ScrollingLayersHelper a more stateful class. r=jrmuizel
This makes ScrollingLayersHelper a non-RAII type class, and instead adds
methods to notify it of when we start processing a new transaction or a
new display item within the transaction. This patch has no functional
changes, it's non-obvious refactoring.
