[fix](compaction) Fix sparse vertical compaction destination offset

[Yukang-Lian]

What changed

• Save the original target-column row count before sparse-column preparation.
• Use the saved row count as the destination offset.
• Add regression coverage for a reserve-only leading BOOLEAN column followed by a nullable fixed-width BIGINT column in the same value group.

Why

The leading value column may reserve capacity without increasing its size. Deriving the destination offset from its post-prepare size can therefore select the wrong position.

Thank you for your contribution to Apache Doris.
Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

1. What problem was fixed (it's best to include specific error reporting information). How it was fixed.
2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
3. What features were added. Why was this function added?
4. Which code was refactored and why was this part of the code refactored?
5. Which functions were optimized and what is the difference before and after the optimization?
