Disable sampleShadingEnable for VulkanHelloAPI

The Vulkan specification states that "If [the sampleRateShading feature] is not enabled, the sampleShadingEnable member of the VkPipelineMultisampleStateCreateInfo structure must be set to VK_FALSE". Since this app doesn't use sample rate shading, this can be disabled so that it can run on Vulkan drivers that don't support this feature.
