vkCmdResolveImage and subpass resolve attachments cannot be used if the
source and destination formats aren't identical per Vulkan spec:
vkCmdResolveImage:
> srcImage and dstImage must have been created with the same image
> format
VkSubpassDescription:
> each resolve attachment that is not VK_ATTACHMENT_UNUSED must have the
> same VkFormat as its corresponding color attachment
