Toyota: use radar in place of abs for platform code ECUs (commaai#31043)

* use radar instead of abs

* str the strenum

* Lexus ES: non-TSS2 probably don't have stop and go without DSU-pull and/or pedal

* remove from NO_STOP_TIMER_CAR. this set is so confusing

* Combine ES & ESH (preferring ESH's DSU msgs)

* ES: forgot substitute

* comment

* Highlander: combine, preferring the hybrid for DSU msg mismatches (0x365 and 0x366)

* remove duplicates and sort

* update docs

* toyota non_essential ECU test

* Lexus RX: combine, preferring hybrid's msgs (they all exist on ICE)

* sort and remove dups

* parameterize so we can test with notebook

* this too

* clean up

* clean up

* tuple makes more sense

* update comments

* update

* update

* update
