    build: Use specific Meson options to enable debug flags
    
    Based on https://gitlab.gnome.org/GNOME/gtk/-/commit/eaef24c527833232bd4725789b0f35304de8123b
    
    Note that TRACKER_DEBUG is disabled in most distro builds as they
    pass `--buildtype=plain`. I recommend distros add `-DG_ENABLE_DEBUG`
    to Tracker Miners' CFLAGS as the overhead is minimal and it helps users
    to provide useful bug reports.
