128bfc06 - [MLAS] Use C-style casting for power vector instructions (#20957)

[MLAS] Use C-style casting for power vector instructions (#20957) ### Description Uses C-style casting for Power vector instructions in `MlasQuantizeLinearInt4Kernel`. ### Motivation and Context Vector commands (e.g., vec_xst) need C-style casting to support various compiler versions. ONNX Runtime CI pipelines do not build with all compiler versions. The recent INT4 PR broke the powerpc build for certain compiler versions because it uses C++-style `static_cast<>`.
