bug: fail to create iceberg table if binary type inside a nested type

[chenzl25]

Describe the bug

The reason is iceberg-rs will try to convert a iceberg binary type to largebinary arrow type, while risingwave converts binary type to binary arrow type. Our type checker relies on arrow type to compare these 2 types, so there is an mismatch.
example

create table t4 (a struct<trace_id bytea>);

create sink xxx from t4 with(
  connector = 'iceberg',
  create_table_if_not_exists='true',
  .....
)
