MCOL-2178 Introduced a dummy replacement for a infinidb_table.

Browse Source 
Used Item attribute getters introduced by 10.4

    Make changes to support Item::CONST_ITEM introduced by 10.4
    as a replacement for INT_,REAL_,STRING_ ITEM.

    Replaced QT_INFINIDB_DERIVED and similar flags
    with correponded flags for Item->print().

    Replaced or commented out infinidb_ variable names with columnstore_
    where applicable.
