Infrastructure changes to support pull-saveLayers-forward task
This is split out of (First pass at pre-rendering saveLayers for GPU - https://codereview.chromium.org/261663003/).
It mainly:
Moves NeedsDeepCopy to somewhere more accessible (so GrPictureUtils.cpp can use it)
Moves ComputeAccelDataKey somewhere more accessible (so GPUPicture test can use it)
Adds unit test for picture saveLayer analysis (done in EXPERIMENTAL_optimize)
Adds new fields to SaveLayerInfo that are needed to pull forward layers
