  Vulkan: Support GL_EXT_EGL_image_storage extension
  
  This extension provides a mechanism for creating texture objects that
  are both EGLImage targets and immutable and removes the possibility of
  implicit orphaning. EGL images created from external sources now
  support types other than 2D. Tests covering the new feature were added
  to ImageTest.cpp.
