KIP-137 — Enhance TopicCommand --describe to show topics marked for deletion

Accepted Admin

Extends `kafka-topics.sh --describe` to include a `MarkedForDeletion: true` indicator for topics pending deletion, and ensures these topics are labeled correctly when combined with `--under-replicated-partitions` or `--unavailable-partitions`. Previously, `--describe` showed no deletion status (visible only in `--list`), causing confusion when a topic appeared under-replicated because it was being deleted.
