Vulkan: Limit mutable texture flush to one update In case there are many updates for a mutable texture, flushing it preemptively can reduce performance, especially if it is done repeatedly. * Added getLevelUpdateCount() to ImageHelper. * Previous mutable textures will now be flushed only if they have exactly one update per mip level/cubemap face (if defined). * This means that mutable textures with no data will also not be flushed. * Added unit tests for single-level texture flushing and situations with no updates or more than one update.
