MultiDisplayList can contain either a SkiaDisplayList or a CanvasOpBuffer. However DisplayList itself still points to the SkiaDisplayList-only wrapper to avoid any std::variant or std::visit overhead just yet. Also fixes a memory leak in CanvasFrontend from an uninitialized std::optional and a few minor leaks in unit tests. Test: build & hwui_unit passes Fixes: 184680809 Change-Id: Ifa6b723b6456f5d3eeac1201e76f337250103d6f Merged-In: Ifa6b723b6456f5d3eeac1201e76f337250103d6f (cherry picked from commit d34d6cec97c8f1be92f676aeb79c83d57cf8c6ba)
