Upload build artifacts separately

Previously, the different builds were firstly uploaded using a single artifact, which was then downloaded to create different ones and eventually deleted.
Now, since builds are created concurrently, the same matrix can be used to directly upload an artifact for each build. It's necessary to use a second job to calculate the checksum related to
each build and save them all in a single .txt file.
