62767060 - kleidiai : fix MUL_MAT support for batched (3D) inputs (#20620)

kleidiai : fix MUL_MAT support for batched (3D) inputs (#20620) * kleidiai : fix MUL_MAT support for batched (3D) inputs The supports_op() check incorrectly rejected MUL_MAT operations with 3D inputs (ne[2] > 1), but the actual compute_forward_qx() implementation handles batched inputs correctly via a loop over ne12. This caused models with Q4_0/Q8_0 weights to crash during graph scheduling when n_seq_max > 1, because weights were placed in KLEIDIAI buffers during loading (tested with 2D inputs) but the runtime used 3D inputs. Also relax the buffer check to allow supports_op() to be called during weight loading when src[0]->buffer is NULL. Fixes #20608 * Kleidiai support_ops should only return true for 3D inputs, not also 4D
