### What problem does this PR solve?
Issue Number: DORIS-26710
Related PR: #64954
Problem Summary:
`test_mow_compact_multi_segments` always enabled the cloud
cumulative-compaction rowset-selection debug point. In local storage mode that
hook was ignored, so the updated default policy could legally merge versions 2
and 3. The case then failed because it still expected a separate third rowset.
This patch selects the rowset-selection debug point according to
`isCloudMode()`:
- cloud mode uses
`CloudSizeBasedCumulativeCompactionPolicy::pick_input_rowsets.set_input_rowsets`
- local mode uses
`SizeBasedCumulativeCompactionPolicy::pick_input_rowsets.set_input_rowsets`
It also replaces stale exact input segment counts with the intended semantic
checks: each selected input rowset must contain multiple segments before
compaction and exactly one segment afterward. The existing query and stale
delete-bitmap cleanup coverage is preserved.
