Everywhere: Use CMake to generate AK/Debug.h.

This was done with the help of several scripts, I dump them here to
easily find them later:

    awk '/#ifdef/ { print "#cmakedefine01 "$2 }' AK/Debug.h.in

    for debug_macro in $(awk '/#ifdef/ { print $2 }' AK/Debug.h.in)
    do
        find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/#ifdef '$debug_macro'/#if '$debug_macro'/' {} \;
    done

    # Remember to remove WRAPPER_GERNERATOR_DEBUG from the list.
    awk '/#cmake/ { print "set("$2" ON)" }' AK/Debug.h.in
