feat: support columns for COPY INTO <TABLE>

[BohuTANG]

Summary

To more easy to do transform in load:
https://databend.rs/doc/load-data/transform/data-load-transform

COPY INTO my_table (id, name)
FROM (SELECT t.id, t.name FROM @mystage t)
FILE_FORMAT = (type = parquet) PATTERN='.*parquet';

[youngsofun]

planning, can manually provide the default values

COPY INTO my_table FROM (SELECT t.id, t.name, false  FROM @mystage t)
FILE_FORMAT = (type = parquet) PATTERN='.*parquet'

instead of

COPY INTO my_table (id, name)
FROM (SELECT t.id, t.name FROM @mystage t)
FILE_FORMAT = (type = parquet) PATTERN='.*parquet'
