Use the new codecov uploader

The python uploader is now phased out [1]

The new uploader is a binary executable for x86-64 (amd64),
so there is no simple way of running it for arm64.
However, the arm64 build for small tests shouldn't affect coverage
anyway (the tests are exactly the same as for amd64), so it is just
skipped for now util the uploader supports this arch, see issue [2]

CODECOV_TOKEN needs to be used now because of issue [3]
