[fix](Outfile) fix bug that the fileSize is not correct when outfile …

…is completed (#23660)

From pr: #22951

1. fix that the fileSize is not correct when outfile parquet/orc file format is completed.
2. max_file_size of orc file format must be multiple of 64MB:
The function add(RowBatch) of orc::Writer would not flush any pending data to the output stream until the strip data is filled. And the defult of strip size of orc file format is 64MB, so we can not get the correct _written_len from orcOutputStream until 64MB data has been writen.
