ggml: fix CLAMP on non-contiguous views (CPU, CUDA) (#29517 )

* ggml: fix CLAMP on non-contiguous views (CPU, CUDA) CUDA clamped ggml_nelements values flat and ignored the view strides. CPU addressed row j as j*nb01 and ignored nb02/nb03. Both now follow the strides of dims 1..3; CUDA supports_op requires contiguous rows, like Metal. test_clamp gains a non-contiguous view case. * cuda: clamp kernel uses fastdiv for the view strides
cuda: BF16/FP16 conversion to f32 chunking (#29442 )

-> - `GGML_OPENVINO_STATEFUL_EXECUTION` is an **Experimental** feature to allow stateful execution for managing the KV cache internally inside the OpenVINO model, improving performance on CPUs and GPUs. Stateful execution is not effective on NPUs, and not all models currently support this feature. This feature is experimental and has been validated only with the llama-simple, llama-cli, llama-bench, and llama-run applications and is recommended to enable for the best performance. Other applications, such as llama-server and llama-perplexity, are not yet supported.
+> - `GGML_OPENVINO_STATEFUL_EXECUTION` is an **Experimental** feature for managing caches internally inside the OpenVINO model on CPUs and GPUs. Use a single slot (`-np 1`). KV caches retain the append-based state layout and sequence-axis optimization. Qwen3.5 adds recurrent cache states in their GGML layouts. Qwen3.5 requires an unsplit graph with model caching enabled and no recurrent rollback. A prompt starting at position 0 resets all states. State save/restore, sequence rewind, context shift, and mid-sequence graph replacement are unsupported. Stateful execution is not effective on NPUs.
 > - `GGML_OPENVINO_LOG_UNSUPPORTED_OPS` emits logs at `WARN` level (`GGML_LOG_WARN`), which requires application log verbosity `--log-verbosity >= 2` (or `-lv 2`).
+> - With `GGML_OPENVINO_COMPILED_MODEL_CACHE_ONLY=1`, use the same compilation settings as the export run. One directory can hold blobs for different models and settings; `GGML_OPENVINO_SPILL_DIR` does not affect the cache key and is ignored in cache-only mode. See [Compiled model cache](../../ggml/src/ggml-openvino/README.md) for the workflow and restrictions.
