  Vulkan: Implement glImportMemoryFdEXT
  
  Allow importing opaque file descriptors into memory objects on linux.
  Currently this just holds onto the file descriptor rather than calling
  vkAllocateMemory immediately. The latter will be easier once we have
  support for suballocation (anglebug.com/2162).
  
  Bug: angleproject:3289
