KT-53154 enumEntries experimental intrinsic stub

Provide an inefficient default implementation and make it "@PublishedApi internal" so it can be safely merged as is. Intrinsics will be added later in follow-up PRs, and then the implementation will be adjusted accordingly Merge-request: KT-MR-10843 Merged-by: Vsevolod Tolstopyatov <qwwdfsad@gmail.com>
