Call SkSurface::flush instead of getting a backend handle in vulkan_swapchain. (#5012)
The old code called getBackendRenderTargetHandle() with a Read access to trigger the surface to flush, however the returned GrVkImageInfo was never used. This how process is equivalent to just calling flush on the surface so do that instead.
