Fix wrong image usage flags in external memory info tests

Fix wrong image usage flags in external memory info tests

According to spec:
  "If usage includes VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT, usage must
   also contain at least one of VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT,
   VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT, or
   VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT."

This change adds adds COLOR, DEPTH or INPUT usage bit alongside TRANSIENT usage.
