Format plan with line number.

Is your feature request related to a problem or challenge?

When I try to complete #8416 , I found it hard to review changes in plan in tpch sqllogictests.

I think the main reason is that CoalesceBatchesExec and RepartitionExec::RoundRobinBatch would make git diff aligns the result in unexcepted position.

Takes q11.slt.part as example, it aligns CoalesceBatchesExec and RepartitionExec::RoundRobinBatch but ignore the -- changes.

If we remove CoalesceBatchesExec and RepartitionExec::RoundRobinBatch, it works well to find the -- changes.

I think adding a line number to the front of each line is a easier way.

Adding a line number seems like a reasonable thing to try to me.

The reason we had -- as the prefix was that sqllogictest stripped off leading spaces

Maybe we can mark it as a good first issue if needed, and slt tests can regenerate by running cargo test --test sqllogictests -- --include-tpch --complete.
