Extend the aarch64-w64-mingw32 prefix to provide ARM64EC libraries alongside standard AArch64 libraries, replacing the separate arm64ec-w64-mingw32 prefix. This aligns with how MSVC distributes ARM64EC libraries and enables the linker to process both targets simultaneously into a single hybrid binary. This extensively utilizes LLVM's -marm64x option, compiling both targets in a single compiler invocation to produce hybrid object files (unlike MSVC tools, which require separate compilation passes).
