chore: combine the logic that triggers automatic compression upon write

[zhyass]

I hereby agree to the terms of the CLA available at: https://docs.databend.com/dev/policies/cla/

Summary

• Unify the automatic compaction logic across INSERT and other mutation operations (including MERGE INTO, etc.).
• Instead of triggering automatic compaction on every write, we now trigger auto-compaction only when the number of imperfect blocks exceeds a configured threshold.
• The rationale: this approach reduces the overhead and performance impact of frequent compaction, avoids unnecessary compaction when write volume or fragmentation is small, and only performs compaction when accumulated fragmentation justifies it — resulting in more efficient and stable storage maintenance.

Tests

• Unit Test
• Logic Test
• Benchmark Test
• No Test - Explain why
