JIRA: CALCITE-3567
Currently, UNNEST(RECORDTYPE(ARRAY)) and UNNEST(RECORDTYPE(MULTISET)) works well, but UNNEST(RECORDTYPE(MAP)) is not supported.

SqlUnnestOperatoruse SCALAR_OR_RECORD_COLLECTION_OR_MAP, and it just checksMULTISETandARRAYinRecordType.This PR tries to add check for
MAPinRecordTypeforSqlUnnestOperatortoo.
