MlasThreadedBufAlloc() and its ThreadedBufHolder guarded the _aligned_malloc / _aligned_free path on _MSC_VER. Non-MSVC Windows toolchains (MinGW, clang) therefore fell through to posix_memalign(), which the Windows CRT does not provide, so the build failed with "'posix_memalign' was not declared in this scope". Guard the aligned-allocation path on _WIN32 instead, in both the holder declaration (mlasi.h) and definition (platform.cpp) so the unique_ptr deleter type stays consistent across translation units, and include <malloc.h> on Windows since MinGW only declares the _aligned_* functions there. The non-Windows posix_memalign / aligned_alloc fallback is unchanged. Fixes #29350
