fix: multipart replication and encrypted etag for sse-s3 (#13171)

Browse Source 
Replication was not working properly for encrypted
objects in single PUT object for preserving etag,

We need to make sure to preserve etag such that replication
works properly and not gets into infinite loops of copying
due to ETag mismatches.
