KAFKA-18486 Migrate testPartitionMetadataFile to use applyDelta in place of deprecated becomeLeaderOrFollower (#19947)
CI / build (push) Waiting to run Details 

Refactor testPartitionMetadataFile to use applyDelta and share
class-level partitions

- Replace deprecated becomeLeaderOrFollower with topicsCreateDelta +
applyDelta
- Test still asserts partition exists, local log exists, and verifies
partitionMetadataFile version (0) and topicId
