turnip: Fill out VkPhysicalDeviceSubgroupProperties

This commit fills out VkPhysicalDeviceSubgroupProperties if present
in a VkPhysicalDeviceProperties2. The values here are simply pulled
from the blob.

Fixes some flakes in dEQP-VK.subgroups.* since dEQP was reading
uninitialized values of VkPhysicalDeviceSubgroupProperties.
