Add optimized WAN 2.2 video workflow

- Added video_wan2_2_14B_i2v_rocm_optimized.json workflow
- Replaced VAE Decode nodes with ROCMOptimizedVAEDecode (2 nodes)
- Replaced KSamplerAdvanced nodes with ROCMOptimizedKSamplerAdvanced (6 nodes)
- Total of 8 ROCM optimizations in the video workflow
- Updated README with both Flux and WAN video workflow downloads
- Ready for testing on gfx1151 architecture
