Code looks good. All the i's are dotted and t's are crossed so to speak.

This change introduces the VK_LOADER_DEVICE_ID_FILTER, VK_LOADER_VENDOR_ID_FILTER and VK_LOADER_DRIVER_ID_FILTER environment variables, where a comma separated list of id ranges can be provided to restrict the enumerated physical devices by the given device, vendor and/or driver ids.
This is mainly needed for the Vulkan SC, but since it's a generic functionality it could be useful also for Vulkan.
e.g. VK_LOADER_DEVICE_ID_FILTER or VK_LOADER_VENDOR_ID_FILTER: "0x10001-0x1FFFF,0x1eb1"
e.g. VK_LOADER_DRIVER_ID_FILTER: "3,7-9"
