ba654836 - Add ORT_ENFORCE for swiglu_fusion==1 in QMoECPU to prevent out-of-bounds read (#27748)

Add ORT_ENFORCE for swiglu_fusion==1 in QMoECPU to prevent out-of-bounds read (#27748) ### Description Add an `ORT_ENFORCE` check in the `QMoECPU` constructor to require `swiglu_fusion == 1` when using SwiGLU activation, preventing an out-of-bounds read. When `swiglu_fusion=0` (the default), `fc1_out_features` is computed as `inter_size` instead of `2*inter_size`. However, `ApplySwiGLUActivation` reads `2*inter_size` values from the FC1 output buffer (via `input_data[2*i]` for `i` in `[0, inter_size)`), causing an out-of-bounds read that produces NaN on Windows x86. This matches the existing validation already present in the `MoE` CPU operator (`moe_cpu.cc:26-27`). ### Motivation and Context - The NaN was caused by a missing `swiglu_fusion=1` attribute. With the default `swiglu_fusion=0`, the SwiGLU activation reads past the allocated FC1 output buffer — an out-of-bounds read. - The `MoE` CPU operator already enforces `swiglu_fusion == 1` for SwiGLU; this change adds the same guard to `QMoECPU` for consistency and safety. - Non-interleaved SwiGLU format (`swiglu_fusion=2`) is not implemented (throws `ORT_NOT_IMPLEMENTED`), and `swiglu_fusion=0` is invalid for SwiGLU, so only `swiglu_fusion=1` is valid.
