feat: add GPIO V2 support and related tests

- Updated  to include  for testing.
- Modified  to include GPIO header and added tests for GPIO functionality.
- Created a new testbench  for GPIO V2, covering register and pad-control contracts.
- Removed obsolete  and its associated test.
- Updated  to include GPIO admin base routing.
- Added a new Python test  for GPIO V2 register and pad-control contract.
- Removed  as its functionality is now covered in .
- Updated memory map tests to ensure GPIO admin base is correctly referenced.
- Adjusted formal filelist generation to reflect changes in GPIO handling.
- Enhanced SOC topology tests to include GPIO interrupt handling.
