What happened

The official source reports this update: b11228: metal: support left and circular padding in GGML_OP_PAD. metal: support left and circular padding in GGML_OP_PAD ( #29561 ) metal: support left and circular padding in GGML_OP_PAD Align Metal with CPU, CUDA and Vulkan: shift the source coordinates by the left paddings, wrap them around with the same wrap_around when circular, and read the source through nb00, which also fixes a right padding of a permuted source. A test case covers it. Drop the f32_4 kernel: its selection is disabled as slower, and it fails two pad cases once enabled.
