s3: Add debug logging for versioning state diagnosis

Temporary debug logging to diagnose test_versioning_obj_plain_null_version_overwrite_suspended failure.

Added glog.V(0) logging to show:
1. setBucketVersioningStatus: when versioning status is changed
2. PutObjectHandler: what versioning state is detected (Enabled/Suspended/none)
3. PutObjectHandler: which code path is taken (putVersionedObject vs putSuspendedVersioningObject)

This will help identify if:
- The versioning status is being set correctly in bucket config
- The cache is returning stale/incorrect versioning state
- The switch statement is correctly routing to suspended vs enabled handlers
