  Revert "Provide default implementation of rx::DisplayEGL"
  
  This reverts commit e82ab75a4ca8f4389a5f23b3a51d9388a92428e2.
  
  Reason for revert: crbug.com/1052772
  
  Original change's description:
  > Provide default implementation of rx::DisplayEGL
  > 
  > Will allow to use EGL instead of GLX on X11.
  > 
  > Meant to be used on modern EGL so it requires the extensions
  > EGL_KHR_no_config_context and EGL_KHR_surfaceless_context.
  > This keeps the default implementation simple (no pBuffer
  > fallback)
  > 
  > Also provide simple WorkerContextEGL.
  >
