According to the Vulkan spec, the VK_KHR_portability_subset extension (different from the enumeration extension) must be enabled on implementations that support it, otherwise validation errors occur.
In addition, this is required for access to portability features that must be turned on for certain samples in the set (e.g. ones that require mutableComparisonSamplers).
