[vk] load VK_KHR_GET_SURFACE_CAPABILITIES_2 on drivers (not a hard requirement) for maintainance 1 (#3514)

fixes VVL, but doesnt make it a hard requirement so drivers which cant load it for some reason just, dont

Validation Error: [ VUID-vkCreateInstance-ppEnabledExtensionNames-01388 ] | MessageID = 0xe5e52180
vkCreateInstance(): pCreateInfo->ppEnabledExtensionNames[3] Missing extension required by the instance extension VK_EXT_surface_maintenance1: VK_KHR_get_surface_capabilities2.
The Vulkan spec states: All required extensions for each extension in the VkInstanceCreateInfo::ppEnabledExtensionNames list must also be present in that list (https://docs.vulkan.org/spec/latest/chapters/initialization.html#VUID-vkCreateInstance-ppEnabledExtensionNames-01388)
