gpu: Load vk functions for querying image/buffer properties

This CL registers a few functions in the Vulkan binding generator script
to be used for importing dma-bufs as VkImages [1] with the end
goal of supporting WebGPU on Chrome OS. In particular, we add:

- vkGetPhysicalDeviceImageFormatProperties2: allows us to query if the
physical device supports importing dma-bufs into Vulkan via the
VK_EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT flag [2].
- vkGetMemoryFdPropertiesKHR: allows us to list the types of memory that
our buffer backed by a dma-buf can be imported as.
- vkGetImageMemoryRequirements2: allows us to list the types of memory
supported by a given VkImage which can be compared to the output of
vkGetMemoryFdPropertiesKHR to determine a suitable memory type for
import.

BUG=996470
TEST=ran the script and used the newly bound functions
