[Windows XPU] Fix MSVC ambiguous symbol error (pytorch#138727)

PT master build with XPU will fail due to MSVC issue of ambiguous symbol error 'std', previously fixed it with MSVC flag in torch-xpu-ops https://github.com/intel/torch-xpu-ops/pull/946/files, but the error is observed in PT master too after 2.5 and oneAPI update.
