Fix https://github.com/clickhouse/clickhouse/issues/91206 when we create a table with statistics and write someting and drop one statistics, it will crash when we read it again. because we assume the serialize and deserialize will have same types statistics. in this fix, we will check if the current metadata contains the serialized statistics, if not, we make a mock statistics and deserialize only to skip it. #91227 (Han Fei).
