rework screenshot API and implementation
- SurfaceFlinger now supports to take a screenshot
directly into an IGraphicBufferProducer
- reimplement the IMemoryHeap screenshot on top
of the above
- reimplement LayerScreenshot such that its
BufferQueue is directly used as the destination
of the screenshot. LayerScreenshot is now a thin
wrapper around Layer
