Add SkOverdrawCanvas to detect overdraw This is the first part of a multi-part change to detect and display gpu overdraw on Android.

#include "SkCanvasVirtualEnforcer.h"
A few bug fixes for SkOverdrawCanvas (1) Use SkNWayCanvas to pass through non-draw canvas calls. (2) Do not count overdraw on the initial canvas clear. (3) Avoid counting overdraw for transparent lattice regions. (4) Respect some properties of input paint.
