icd: Add VkPhysicalDeviceDriverProperties

This commit adds support for the VkPhysicalDeviceDriverProperties struct
in the output of vkGetPhysicalDeviceProperties2. This is useful for users
of Mock ICD wishing to know the version of MockICD used. The driverInfo
field is used for this purpose and contains the git branch & tag info data.
The use of Git in CMake is how the information is seamlessly gotten and
provided to the source code in the form of compile definitions.
