Enhance CI workflow for CGO dependency installation and testing

- Update the installation step for GCC to include checks for various package managers
- Improve error handling and output messages for GCC installation
- Modify test execution to conditionally enable CGO based on GCC availability
- Ensure compatibility with non-CGO builds by setting CGO_ENABLED appropriately
