Complete replacing member data with decorations in the ir tree (elastic#64825)

This change replaces all the member data in the ir nodes with decorations instead. This completes the 
transition to a decoration system in the ir tree. This change allows for maximum flexibility when 
modifying existing phases or adding additional phases.
