sycl: support reordered Q4_K/Q5_K/Q6_K MoE MUL_MAT_ID (#24452)

* sycl: support reordered Q4_K and Q5_K MoE MUL_MAT_ID

Extend reordered-weight handling to fused MoE MUL_MAT_ID for Q4_K and Q5_K expert tensors and add Q5_K reordered DMMV coverage. Unsupported 3D reorder cases now fall back instead of aborting.

* sycl: extend MoE reorder to Q6_K mul_mat_id
