[function]cardinality(HLL)

[wangsimo0]

StarRocks support hll_cardinality https://docs.starrocks.io/docs/sql-reference/sql-functions/scalar-functions/hll_cardinality/ however, in trino's compatibility, trino support hll type's cardinality in function cardinality().

if starrocks support hll input in cardinality(), it will make starrocks be more compatible with trino in trino's sql_dialect
