Yongqiang YANG a978be32a6 [fix](schema_change) remove shadow prefix of schema for tablesink (#18822 )

LSC updates tablet's schema in writing. Be optimized adding columns via linked schema change and
it distinguishes adding by comparing column name. e.g. if new column's name is not found in old schema,
then it is a newly-add column.

When a table is under schema-changing, it adds __doris_shadow_ prefix in name of columns in shadow index.
Then  writes during schema-changing would bring schema with __doris_shadow_ to be.
If schema change request arrives at be after writes, then be do it as a add-column schema change due to 
__doris_shadow_ is not in base tablet.
