Add validations on texture sample counts in B2T and T2B copies

This patch adds validations on the sample count of the textures used in
buffer-to-texture and texture-to-buffer copies. Vulkan SPEC requires the
textures used in vkCmdCopyBufferToImage and VkCmdCopyImageToBuffer must
have a sample count equal to VK_SAMPLE_COUNT_1_BIT.
