handwired/ortho5x13: layout macro refactor

Discovered the LAYOUT_compact macro didn't compile in QMK Configurator. Realized the reason for that was that it automatically prepends `KC_` to every keycode received.

Renamed the macro to LAYOUT_kc so Configurator will ignore it.

Also changed the file to use the #pragma once include guard because I was in here anyway.

Add new brightness aliases to keycodes_basic.md
