Avoid including explain.h in explain_format.h and explain_dr.h

Browse Source 
As per a suggestion from Tom Lane, we do this by declaring "struct
ExplainState" here and refer to that rather than "ExplainState".

Also per Tom, CreateExplainSerializeDestReceiver was still defined
in explain.h in addition to explain_dr.h. Remove leftover prototype.
