[Enhancemant](HLL) support export doris hll/bitmap data type

[GoGoWen]

Proposed changes

when we export data from table which has HLL/BITMAP to iceberg table, we can not export the HLL and BITMAP column. we just want to export, as we have another way to query the HLL/BITMAP in Doris by give the column type HLL and BITMAP.

Can you post a usage example for this? Because I saw that Doris does not support converting Bitmap and HLL type data into arrow for spark to read ?

Later we can make a pr to support doris query Bitmap and HLL type, now we want to export the data to iceberg table because of disk capacity limitation
, and which also need to support query in doris with iceberg table.
