handle the locks properly for multi-pool callers (#20495)

- PutObjectMetadata()
- PutObjectTags()
- DeleteObjectTags()
- TransitionObject()
- RestoreTransitionObject()

Also improve the behavior of multipart code across
pool locks, hold locks only once per upload ID for

- CompleteMultipartUpload()
- AbortMultipartUpload()
- ListObjectParts() (read-lock)
- GetMultipartInfo() (read-lock)
- PutObjectPart() (read-lock)

This avoids lock attempts across pools for no
reason, this increases O(n) when there are n-pools.
