Vulkan: Remove ImageHelper::mImageAndViewGarbage This was introduced in crrev.com/c/3449450. At that time this is necessary, because we can not copy mUse for immediate view garbage collection. Now with recent work, mUse is copyable, we no longer need to accumulate the view garbage. They can be released immediately with a copy of image's mUse.
