Fix artifact v4 upload above 8MB (#31664)

Browse Source 
Multiple chunks are uploaded with type "block" without using
"appendBlock" and eventually out of order for bigger uploads.
8MB seems to be the chunk size

This change parses the blockList uploaded after all blocks to get the
final artifact size and order them correctly before calculating the
sha256 checksum over all blocks

Fixes #31354
