fd55dd9e9d stepper: Also ensure minimum time after dir change and next step 
In practice the host will not schedule any steps immediately after a
direction change (due to acceleration limits and the host
"step+dir+step filter").  However, there is also no harm in enforcing
a minimum duration in the mcu.

885f63cff0 stepper: Ensure minimum time between step pin and dir pin change 
Commit 8faed8d9 made it possible to utilize stepper_event_full() while
utilizing tmc "step on both edges" optimation.  That commit would
ensure a minimum step pulse duration, but it did not ensure a minimum
duration between step pin and dir pin changes.  Commits 0d27195f and
554ae78d optimized the gpio handling on stm32h7 chips, which could
potentially cause a very small amount of time between step pin and dir
pin changes.

Enforce a minimum time after a step pin update before updating the dir
pin.

s->position in stepper_load_next().  This simplifies the code and
