RFR: 8279997: check_for_dynamic_dump should not exit vm [v2]

[Yumin Qi]

> Hi, please review
>   When run with -Xshare:auto and the base archive could not be loaded, vm should not exit in DynamicArchive::check_for_dynamic_dump, instead, it should continue without sharing.
>   The fix is the run will continue but print out warning to remind user of using -Xlog:cds for more information.
> 
> Tests: tier1,tier4
> 
> Thanks
