feat: refactor GPIO Interface and Migrate Legacy Code

- Updated the GPIO interface in multiple modules to use the new user_gpio_if structure instead of the legacy gpio_if.
- Modified the ip_apb_wrapper, ip_nmi_wrapper, user_ip_design_template, user_ip_top, and user_ip_wrapper to reflect the new GPIO interface.
- Increased the USER_GPIO_NUM from 16 to 32 in mdd_config.svh to accommodate more GPIOs.
- Removed legacy GPIO handling from retrosoc and retrosoc_asic modules.
- Implemented a migration script in generate_mpw.py to automatically update legacy GPIO ports in source files.
- Added tests for the new GPIO user interface and ensured proper functionality through gpio_user_mux_tb and gpio_user_mux.py.
- Created new makefiles for IP MDD configurations to support the updated GPIO structure.
- Updated regression tests to include new configurations and ensure compatibility with the changes.
