  Pass the attribute map to egl::Sync::initialize.
  
  The attribute map was typically passed to the impl objects in the
  constructors. Instead, pass it to the initialize function. This removes
  the need for many member variables in different backends and opens up
  the future optimization of re-using sync objects by calling
  initialize on them with new attributes.
