    Fix arch detection ifdefs in glib/valgrind.h
    
    Don't assume that __MINGW32__ implies x86; Windows runs on ARM/ARM64
    as well, and there are mingw toolchains that target those architectures.
    
    This mirrors how the MSVC part of the same expressions are written,
    as (defined(_WIN32) && defined(_M_IX86)) and
    (defined(_WIN64) && defined(_M_X64)) - not relying on _WIN32/_WIN64
    or __MINGW32__/__MINGW64__ alone to indicate architecture.
