While working on #4378 I noticed a funny problem: the blinking system LED was on during deep-sleep. Initially I thought it was some weird sleep hw config thing but it turns out it was easier but more pervasive. We had two different preprocessor symbols which both meant approximately the same thing LED_INVERTED and LED_STATE_ON (though their polarity was opposite). Some variant files were setting one, others were setting the other, and others were setting both. heh. In the case of the board I was testing (seeed tracker wio 1100) it was only setting one and the default behavior for the other (for all boards) was incorrect. So I did a grep and it seems like LED_STATE_ON was used more often, so I kept that one and removed LED_INVERTED everywhere.
