RFR: 8265794: Remove ProblemList-non-cds-mode

[Mikhailo Seledtsov]

Please review this trivial change.

This list has been empty for a long time, and no changes in history since Oct 2018. If we see any issues in non-CDS mode (-Xshare:off) testing in the future (which is very unlikely), we should simply use generic ProblemList to exclude such failing tests.
