s3: add multi-part-upload support for If-Match and If-None-Match

Browse Source 
#8947 implemented support for the If-Match and If-None-Match headers for S3 PUT
Object requests; however, this support did not extend to multi-part copy and
upload requests. These headers are implemented via inclusion in the
CompleteMultipartUpload request.

This updates the auto generated code also which was needed for multipart copy.
