  EGL: implement EGL_EXT_buffer_age
  
  Add extension flag.
  Add Validation check to surface query.
  Enable extension for vulkan.
  Modify AcquireNextImage to ++frame count and tag images
  with frame number.
  Buffer age is the difference between current frame count
  and the tagged frame number on the buffer.
  getBuffeAge may need to trigger AcquireNextImage to be current.
  Pass through egl extension and query.
  Add EGLBufferAgeTest
  
  Test: angle_end2end_test --gtest_filter=EGLBufferAgeTest
  Test: angle_deqp_egl_tests
  --deqp-case=dEQP-EGL.functional.buffer_age.*
