Brecht Van Lommel b8b7f71520 Vulkan: Implement native handles for pixel buffers 
* Pixel buffer is always allocated with export and dedicated memory flags.
* Returns an opaque file descriptor (Unix) or handle (Windows).
* Native handle now includes memory size as it may be slightly bigger
  than the requested size.
