with the pi4, WAKE_ON_GPIO=1 would cause the VPU firmware to go into a low power state, with a gpio edge interrupt setup on gpio4
and once that is triggered, it will resume booting
and POWER_OFF_ON_HALT=1, means that it asks the PMIC to turn the power rails off, and then the SoC is just dead, until an external trigger resets things
i'm not sure how exactly the pi5 changes things, still need to play with those settings and see what happens
