[Java] Sql type DATE should correspond to DateDayVector

[asfimport]

According to SQL convertion, sql type DATE should correspond to a format of YYYY-MM-DD, without the components for hour/minute/second/millis

Therefore, JDBC type DATE should correspond to DateDayVector, with a type width of 4, instead of 8.
