Prior to this change, TransformationReplaceIdWithSynonym was designed to be able to replace an id with some synonymous data descriptor, possibly necessitating extracting from a composite into a fresh id in order to get at the synonymous data. This change simplifies things so that TransformationReplaceIdWithSynonym just allows one id to be replaced by another id. It is the responsibility of the associated fuzzer pass - FuzzerPassApplyIdSynonyms - to perform the extraction operations, using e.g. TransformationCompositeExtract.
