Return error for requested unsupported features

Per the Vulkan spec:

   If any requested feature is not supported, vkCreateDevice
   must return VK_ERROR_FEATURE_NOT_PRESENT.

I've added a templated function to vk::PhysicalDevice that compares
requested features against the results of a call to getFeatures2. This
keeps the places that reference support for a feature localized to
VkPhysicalDevice.cpp.

Tests: dEQP-VK.api.device_init.create_device_unsupported_features
