b062ba73 - opencl: port fused ssm_scan kernel (Mamba-2, d_state in {128, 256}) to GPU (#26439)

opencl: port fused ssm_scan kernel (Mamba-2, d_state in {128, 256}) to GPU (#26439) * opencl: port fused ssm_scan kernel (Mamba-2, d_state in {128, 256}) Fold the fused per-token SSM_SCAN recurrent step from opencl/gdn-qwen36-35b onto the unified base. Previously SSM_SCAN fell back to CPU here; now scalar-A Mamba-2 with d_state in {128,256}, all-f32, runs on GPU. Other shapes (incl. Mamba-1 element-wise A) still fall back. test-backend-ops -o SSM_SCAN passes on Adreno X2-90. opt-out via GGML_OPENCL_DISABLE_SSM_SCAN=1. * opencl: cleanup * opencl: require K == 1 --------- Co-authored-by: Li He <lih@qti.qualcomm.com>
