feat: Add support for SKY130 OpenRAM SRAM integration

- Introduced  to handle the preparation of the SKY130 OpenRAM SRAM views.
- Updated  to download and prepare the SRAM archive during PDK setup.
- Enhanced OpenSTA and Yosys configurations to accommodate SRAM macro integration.
- Added Verilog simulation models for GF180 and SKY130 SRAM macros.
- Implemented tests for SRAM setup and validation, ensuring correct integration and functionality.
- Updated various Makefiles and scripts to support SRAM size and macro configurations.
