MicroPython Codegen Scripts can't deal with formatted sources

Linebreaks in the MP_REGISTER_MODULE macro call will lead to build errors. This can be fixed by disabling formatting for the MP_REGISTER_MODULE macro with a comment to turn clang-format off. This needs to be in every C-module file.

/* clang-format off */
MP_REGISTER_MODULE(MP_QSTR_leds, leds_module, MODULE_LEDS_ENABLED);
