Which issue does this PR close?

Defer task spawning in SortPreservingMergeExec to first poll #21329

Rationale for this change

I would like for DataFusion to be more explicit about parallelism / concurrency.
SortPreservingMergeExec is one of a few nodes that executes the stream eagerly, i.e. it spawns buffered tasks immediately, even before any batch is polled from the output stream.

This makes it difficult to control/limit pipeline parallelism and reduce (memory) resources.
Also it makes short-circuiting of complex plans less useful as it might already have executed a large part of the plan.

What changes are included in this PR?

Introduces a LazySortPreservingMergeStream that defers executing input partitions, spawning buffered tasks, and building the streaming merge until the first poll_next() call. The single-partition and zero-partition paths are unchanged.

In practice, this has no big effect, as SortPreservingMergeExec is usually on the root of queries (in plans a partitionSortExec is more common as we usually don't need/avoid global order inside plans)

How are these changes tested?

All existing tests pass (17/17).

🤖 Generated with Claude Code

Previously, SortPreservingMergeExec eagerly executed all input partitions and spawned buffered tasks in execute(). This meant that even if the output stream was never polled, all tasks would be spawned. This changes the multi-partition path to use a lazy stream that defers spawning and building the streaming merge until first poll_next().
