feat: add USB2 support and related tests

- Introduced a new USB2 transaction engine testbench to validate the functionality of the USB2 transaction engine.
- Updated clock and reset domain tests to include USB2 ULPI crossings.
- Enhanced memory map tests to verify USB2 base addresses and performance offsets.
- Modified pin map tests to ensure USB2 ULPI pins are correctly generated.
- Updated SOC topology tests to account for USB2 peripherals and IRQ mappings.
- Added static timing analysis constraints for USB2 clock domains.
- Created dedicated USB2 tests for various components including packet RAM, descriptor validation, and transaction engine.
- Implemented a register parity test to ensure ABI consistency between RTL and C header definitions.
