Experimental, untested.
Migrate high-side switch to a schematic-defined block, and add a variation that has a zener clamp on the gate, for when the input voltage is greater than a reasonable gate voltage. For now, the user has to manually opt-in by specifying a clamp_voltage to HighSideSwitch.
Update DRV8313 to ground the NC pins and unused comparator output, per the datasheet example layout.
