Add GPU features: production SoC, enterprise modules, CI/CD & tests

[VidhyaSanjeevi]

Summary

Based on interest, contributed as an exploring project. Used Claude Model for building this.

• Production GPU SoC: Full system-on-chip with PCIe controller, display controller, command processor, interrupt controller, clock/reset management, geometry engine, and render output unit
• Enterprise GPU modules: Tensor processing unit, ray tracing unit, DMA engine, ECC controller, power management, debug controller, video decode unit
• Core enhancements: Cache (L1/instruction), branch divergence, memory coalescing, pipelining, optimized ALU/decoder/scheduler, shared memory, barriers, atomics, warp scheduling, performance counters
• Graphics hardware: Rasterizer with 24 comprehensive tests, framebuffer, texture unit, TLB, load-store queue
• Tiny Tapeout 7 adapter: Adapter module for TT07 integration
• CI/CD pipeline: GitHub Actions workflow with automated testing for all modules
• VLSI/FPGA support: Constraints (SDC/XDC), floorplan, UPF power intent, DFT scan config
• Compatibility fixes: cocotb 2.0/1.9.x, iverilog 11, sv2v, Ubuntu 22.04

Test plan

• All existing tests pass (cocotb-based)
• GPU SoC integration tests - 16 tests passing
• Enterprise module verification - 69 tests
• Production module unit tests covering all new hardware blocks
• CI/CD pipeline validates on push
