[Vulkan][Target] Added the driver name to the vulkan target string. (#…

…8882)

Driver name (e.g. "NVIDIA", "radv", "AMD open-source driver") is read
from the `driverName` property in
[VkPhysicalDeviceDriverProperties](https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkPhysicalDeviceDriverProperties.html),
or is left as `"unknown_driver_name"` if the driver does not support
querying the driver name.
