Instead of using a runtime callback to register the console commands, put them in a special linker section. So we can do a macro to "register" them during the build. It saves 684 bytes and a few microseconds at startup. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BUG=None TEST=run a few commands from the BDS command line.
