RFR: 8303422: Use a common functions to exit the VM for -Xshare:dump and CDS errors

Thu Apr 13 15:34:49 UTC 2023

Currently, we have ad-hoc calls to os::_exit(0), vm_exit_during_initialization() and vm_direct_exit() in cases where there are dumptime or runtime errors for CDS. This patch introduces intuitively named methods for exiting the VM when there are dumptime/runtime errors and when dumping is finished. Verified with tier 1-4 tests.
