Fixes #22709

Summary

The original "batch_create_segment_to_index_task" task would store all the contents of the file as the parameter "content" in the AMQP, and the size of the MQ message could be very large, even exceeding the "max_message_size" configuration of RabbitMQ, which could cause Celery to lose the task.
This modification changed the parameter of "batch_create_segment_to_index_task" from "content" to "upload_file_id". During the execution of the task, the file was downloaded and further processed to avoid large MQ messages.
If the Celery broker uses Redis, this modification can also prevent the occurrence of large Redis keys.
