listing: improve listing of encrypted objects (#14667)

Browse Source 
This commit improves the listing of encrypted objects:
 - Use `etag.Format` and `etag.Decrypt`
 - Detect SSE-S3 single-part objects in a single iteration
 - Fix batch size to `250`
 - Pass request context to `DecryptAll` to not waste resources
   when a client cancels the operation.
