Subject: [PATCH] fix(database/gdb): clickhouse can not support
 int128/int256/uint128/uint256 (#4370)

When use clickhouse and use field type int128/int256/uint128/uint256. It
can not work well and it will return 0 value.
Add the new field types to let it work well.

By the way, the data struct field need be set to big.Int when use the
types.
