ci: update coverage upload to use coverage.info files

Replace profraw artifact uploads with coverage.info files generated by make generate-codecov
in smoke, unit test, and takeover jobs for more accurate coverage reporting.

Simplify artifact download steps in nydus-coverage job to match new coverage info files and ensure
correct coverage data is uploaded to Codecov.
