  EGL: Implement EGL_ANDROID_native_fence_sync on vulkan
  
  Check the following -
  1. Vulkan ICD supports VK_KHR_external_fence_fd
  2. ExternalFenceProperties and ExternalSemaphoreProperties
     support Android FD.
  
  eglCreateSync - if FD was provided import to VkFence,
                  else create VkFence with new FD and then
                  flush and submit VkFence on next vkQueueSubmit.
  
  eglGetSyncAttrib - for status call vkGetFenceStatus.
  
  eglDupNativeFenceFdANDROID - return FD from vkGetFenceFD call.
  
  eglClientWaitSync - call vkWaitForFences.
  
  eglWaitSync - dup FD, create VkSemaphore and import FD, then
                flush() and add VkSemaphore to next vkQueueSubmit
                as a waiting semaphore.
  
  Extended end2end test suite with nativefence test cases.
  
  Bug: angleproject:2517
  Test: angle_end2end_tests --gtest_filter=EGLSyncTest.AndroidNativeFence_*
