anv: check support for enabled features in vkCreateDevice()

From Vulkan spec, 4.2.1. "Device Creation":

  "vkCreateDevice verifies that extensions and features requested in
   the ppEnabledExtensionNames and pEnabledFeatures members of
   pCreateInfo, respectively, are supported by the implementation."
