  Vulkan: Implement EGL_KHR_partial_update
  
  This change provides a trivial implementation of partial
  update that does nothing, making apps that want this
  extension happy. A possible efficient Vulkan implementation
  would use the damage set to narrow down render area, but it
  appears to only be useful for only some TBDR hardware.
