opencl: skip the Adreno KQ/KQV image kernels for multi-stream batches (#26189)

opencl: skip the Adreno KQ/KQV image kernels for multi-stream batches (#26189)

The Adreno KQ/KQV image1d kernels (ggml_cl_mul_mat_kq_kqv_adreno) ignore
dim 3 entirely: the sub-buffer covers only nb02*ne02 bytes and the kernel
receives no ne03/ne13/nb03/nb13 arguments. With the unified KV cache,
multi-sequence batches (e.g. llama-perplexity with its default -b 2048,
n_seq=4, or a multi-slot llama-server) present KQ/KQV as 4D tensors with
ne3 = n_stream, so every stream past the first reads the first stream's
K/V and produces garbage. Flash attention masks the bug where it is
enabled; devices where FA is declined (e.g. Adreno 740) hit it with
default settings.

Route ne03/ne13 > 1 to the general path, which handles dim 3, and honor
view_offs when creating the sub-buffers (currently always 0 for tensors
reaching this function, but the function would silently misread any
future view).
