Bug: 17208461 There's a potential race condition between HardwareRenderer.destroy() being called (which calls destroyCanvasAndSurface()) and the renderer being finalized (which is what calls freePrefetchedLayers), during which time it's possible we get a TRIM_MEMORY_COMPLETE and destroy the EGL context. Fix this race condition by moving stopDrawing() and freePrefetchedLayers() into destroyCanvasAndSurface() where they should have been in the first place. Also, if we hit the assertion failure, dump the current state of Caches to try and provide more context for the failure. Change-Id: Ife0ba3562041e8b08e87e3e13640472b3004eed6
