Zig's bundled libc++/libc++abi conflicts with the MSVC C++ runtime headers (vcruntime_typeinfo.h, vcruntime_exception.h, etc.) when targeting native-native-msvc. This caused compilation failures in the SIMD C++ code due to -nostdinc++ suppressing MSVC headers and libc++ types clashing with MSVC runtime types. Skip linkLibCpp() for MSVC targets across all packages (highway, simdutf, utfcpp) and the main build (SharedDeps, GhosttyZig) since MSVC provides its own C++ standard library natively. Also add missing <iterator> and <cstddef> includes that were previously pulled in transitively through libc++ headers but are not guaranteed by MSVC's headers.
