Handling tail-corrupted entry in remote WAL

What type of enhancement is this?

Tech debt reduction

What does the enhancement do?

By default, we only tolerate tail-corrupted entry in remote WAL. However, we should trigger a flush once the region leader detects the tail corrupted entry during the replay(updates the last_flushed_entry_id in the manifest).
