VkPhysicalDeviceFeatures only contains VkBool32 members, and is also
described by the spec as a "structure that contains boolean indicators
of all the features to be enabled", as well as "For each feature, a
value of VK_TRUE specifies that the feature is supported on this
physical device, and VK_FALSE specifies that the feature is not
supported". Hence we can safely process it as an array of VkBool32.

This is also more likely to return false early when a requested feature
is not supported.
