Fix the missed setting of DescriptorSetLayout in chapter 24/25/26

[vbtang]

While I'm learning the tutorial of vulkan by running the samples one by one, I found some settings of DescriptorSetLayouts are missed. So these samples crashed and printed following logs in the console when I try to run them. And It seems that Chapters 22 and 23 also require the same fix?

validation layer: type { Validation } msg: vkCreateGraphicsPipelines(): pCreateInfos[0].pStages[0] SPIR-V (VK_SHADER_STAGE_VERTEX_BIT) uses descriptor [Set 0, Binding 0, variable "ubo"] but the binding was not declared in the VkPipelineLayoutCreateInfo::pSetLayouts[0].
Possible VkDescriptorType that could be used are: VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC or VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK or VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER.
The Vulkan spec states: If a resource variable is declared in a shader and layout is not VK_NULL_HANDLE, the corresponding descriptor set in layout must match the shader stage (https://docs.vulkan.org/spec/latest/chapters/pipelines.html#VUID-VkGraphicsPipelineCreateInfo-layout-07988)
validation layer: type { Validation } msg: vkCmdBindDescriptorSets(): firstSet (0) plus descriptorSetCount (1) is greater than VkPipelineLayoutCreateInfo::setLayoutCount (0) when pipeline layout was created.
The Vulkan spec states: The sum of firstSet and descriptorSetCount must be less than or equal to VkPipelineLayoutCreateInfo::setLayoutCount provided when layout was created (https://docs.vulkan.org/spec/latest/chapters/descriptorsets.html#VUID-vkCmdBindDescriptorSets-firstSet-00360)
