manual_stepper: Implement "drip moves" for manual stepper STOP_ON_ENDSTOP

Browse Source 
Currently, `MANUAL_STEPPER STOP_ON_ENDSTOP=1` type commands will move
until hitting the endstop, but it will still always consume the total
amount of move time.  That is, following moves can't be started until
the total possible time of the homing move is completed.

Implement "drip moves" so that the code only schedules the movement in
small segments.  This allows following movements to be scheduled
without a significant delay.

20250417: SPI devices using "software SPI" are now rate limited.
Previously, the `spi_speed` in the config was ignored and the
transmission speed was only limited by the processing speed of the
