vk_texture_cache: Fix invalidated pointer access

Browse source 
The vulkan ImageView held a reference to its source image for rescale status checking. This pointer is sometimes invalidated when the texture cache slot_images container is resized.
To avoid an invalid pointer dereference, the ImageView now holds a reference to the container itself.
