Chris Lu eed5e8cdf6 s3: return the multipart object checksum in the CompleteMultipartUpload response (#11101)
* s3: return the multipart object checksum in the CompleteMultipartUpload body

S3 carries the flexible-checksum members of CompleteMultipartUploadResult in
the XML body, not in response headers, so every SDK read back an empty
checksum from an upload that asked for one.

* s3: echo the checksum algorithm and type from CreateMultipartUpload

The upload directory already records both, but the response dropped them, so a
client could not confirm which checksum its parts had to carry.

* test: multipart upload reports the object checksum it was asked for

Covers every algorithm end to end: the create response echoes the algorithm and
type, the complete response carries the checksum, and it matches what a later
HEAD reports.
