abotsis 60b68a6279 sycl : fused MoE mul_mat_vec_q for TG (#21920) ... * sycl : fused MoE mul_mat_vec_q for TG Create an MMVQ kernel so ggml_sycl_mul_mat_id can consolidate n_experts_used matmuls in a single kernel launch. The kernel also reads expert IDs directly, removing a per-call host sync. This is similar to the CUDA backend's ggml_cuda_mul_mat_vec_q* paths. All types supported in the current MMVQ are supported here as well: Q2_K, Q3_K, Q4_K, Q5_K, Q6_K, Q4_0, Q4_1, Q5_0, Q5_1, Q8_0 It will fall back to the existing per-expert path when src0 has been rewritten by opt_for_reorder(), and for any shape the fused path doesn't handle. test-backend-ops passes for supported type/shape combos.
