ci: Collect and upload spectests coverage

This modifies "coverage-gcc" job. All Fizzy tests are uploaded to
codecov with flag "unittests". Additionally, the coverage from the
spectests run is uploaded with "spectests" flag.

Also update codecov config: use true/false, disable require_ci_to_pass,
enable "impacted files" and "flags" GitHub comment.
