[SYSTEMDS-3775] Revert components

This commit reverts the recent addition of components in the
code coverage utility. Unfortunately, the components did more
than anticipated, because they add more checks to the commits
and were not visible in the PR that was trying their behavior.

The intended behavior was to have coverage measurements and easy
selection of sub-packages in the codecov webpage (this worked on the PR).
Instead, it also added extra unintended 'Actions' that had to be passed
for validation once merged to main.

Furthermore, the Python upload of code coverage did not work once
merged to main, therefore that change is reverted as well.
