build: Streamline workflows with nvme-cli

Make the build workflow similiar to the one we have in nvme-cli.

- Explicitly configure release/debug build
- Explicitly set wrap mode
- Explicitly enable/disable --werror (disable it for fallbacks)
- Cleanup install depedencies
- Merge muon.yml into build.yml
- Move coverage into coverage.yml
