feat: refactor NMI interface and remove unused variables

- Removed CORE and IP variables from common.tcl and synth.tcl scripts.
- Updated yosys.mk to exclude CORE and IP from environment variables.
- Modified bus_fault_tb to enhance NMI interface with management and user NMI signals.
- Added user access denial handling in bus_fault_tb.
- Updated pll_ctrl_tb and sysctrl_fault_tb to reflect changes in NMI interface.
- Adjusted test_gpio_user_mux.py to remove IP_MDD definition.
- Enhanced memory map tests to include user extensions and ensure proper generation.
- Updated test_script_tools.py to reflect changes in core management and user extensions.
- Refined topology tests to ensure user APB target is always added.
- Adjusted tech cell configuration tests to use simplified profile paths.
- Improved user extensions tests for scalar bindings and slot validation.
