RFR(S) 8189840: CheckCachedResolvedReferencesApp has no cached resolved references

[Jiangli Zhou]

Please review the fix for 8189840. CheckCachedResolvedReferencesApp currently is still a closed AppCDS test. The following webrev only contains the WhiteBox change with the new API (WhiteBox.openrchiveHeapObjectsMapped()) added. CheckCachedResolvedReferencesApp calls the new API to detect if the ‘open archive’ heap objects are mapped successfully in the current JVM execution. CheckCachedResolvedReferencesApp test change is not included in the webrev.

Tested on linux-x64. Also running hs-tier1, hs-tier2 tests.
