Fix merge scan summary (#11392)

* fix(scan): fix ScanStatus when merge NativeReportSummary

1. Running and success status is high priority when merge ScanStatus of
NativeReportSummary, otherwise chose the bigger status.
2. Merge scan logs of referenced artifacts when get the scan logs of
image index.

Closes #11265
