RFR: 8304484: CDS dynamic dumping incorrectly leads to "Error occurred during initialization of VM"

[Matias Saavedra Silva]

When a non-empty directory is found in the shared path table, the follow error is emitted:
 ```
Error occurred during initialization of VM
 Cannot have non-empty directory in paths


While this makes sense for static dumping, which occurs during initialization, it is not true for a dynamic dump. To remove confusion, path failures exit with `vm_exit_during_cds_dumping`. Verified with tier 1-5 tests.
