branch-4.0: [enhance](job) support adaptive batch param for routine load job

[sollhui]

What problem does this PR solve?

pick #56930 and #57967

Users may set the max batch interval relatively small for visibility, which may result in insufficient throughput and data backlog when traffic is high. We propose an adaptive max batch interval scheme aimed at prioritizing throughput over visibility during data backlog
