[Oracle][Tests] Enhance Point convertion test

Instead of using 'SDO_UTIL.FROM_WKTGEOMETRY' to generate `SDO_GEOMETRY` object
for Point, the `testdata` generate Point and MultiPoint with `SDO_POINT_TYPE`
or `SDO_ELEM_INFO_ARRAY` and `SDO_ORDINATE_ARRAY`.

With this way of creating Point and MultiPoint, we can test the way Point and
MultiPoint are converting to WKB.
