Enhance MySQL/MariaDB development headers installation in upgrade scripts

- Added installation steps for MySQL/MariaDB development headers in both cyberpanel.sh and cyberpanel_upgrade.sh to support the mysqlclient Python package.
- Implemented checks for different operating systems (Ubuntu, Debian, CentOS, RHEL, etc.) to ensure the correct packages are installed.
- Enhanced error handling during Python requirements installation with fallback options for mysqlclient.
- Verified the installation of MySQL development headers using pkg-config.
