feat: add crypto accelerator support and related tests

- Modified DMA error testbench to include crypto input and output AXI4 stream interfaces.
- Updated DMA register testbench to integrate crypto AXI4 stream interfaces.
- Enhanced SOC IRQ topology test to account for new crypto IRQs.
- Added WS2812 DMA testbench modifications for crypto interfaces.
- Introduced new Python tests for crypto primitives (AES, SHA, RSA) and APB register paths.
- Implemented register parity tests to ensure synchronization between RTL and SDK constants.
- Expanded DMA tests to validate crypto streaming endpoints.
- Updated memory map tests to include crypto address definitions.
- Adjusted SOC topology tests to reflect changes in IRQ mappings and peripheral counts.
