Separate tests with coverage and without coverage (#1953)

Running code coverage slows down the run by ~20%.
The commit separates the tests into two different jobs
based on the operating system. The "Tests (Coverage)"
job runs the tests with coverage and is only triggered
on the "ubuntu-latest" OS, while the "Tests (No Coverage)"
job runs the tests without coverage on other OSes.
This change improves the test workflow and ensures that
coverage only runs on the os that does uploads the result
to Codecov.
