feat: Add firmware installation and module dependency resolution

- Add Alpine firmware package installation support
- Implement recursive module dependency resolution using modinfo
- Add config/firmware.conf for NIC firmware selection
- Enhanced initramfs_setup_modules with dependency tracking
- Firmware installation integrated into main build process

Features:
- Automatic dependency resolution for kernel modules
- Alpine's separate firmware APK packages for optimal size
- Stage1/Stage2 module loading with complete dependencies
- No duplicate modules between stages
