Cleanup: using the proper Image subregion structure

VkImage use different structures to represent subregions:
- VkImageSubresource (Single mip level, single layer)
- VkImageSubresourceLayers (Single mip level, multiple layers)
- VkImageSubresourceRange (Multiple mip levels, multiple layers)

This cl changes the subregion structure used in vk::Image and in the
Blitter so that it contains the information required for the current
task and no more than that.
