feat: comapction aware disk cache region eviction

[MrCroxx]

Is your feature request related to a problem? Please describe.

Currently, the disk cache region to evict is picked following the 2 rules:

1. Pick by invalid ratio > 0.8.
2. Pick in FIFO order.

However, disk cache is currently not compaction-aware, which means the invalid ratio is only calculated by removal ratio, no compacted blocks included.

Describe the solution you'd like

Actively remove compacted blocks, or introduce a disk cache eviction picker to solve.

Describe alternatives you've considered
