Advice users to issue a FIRMWARE_RESTART command on a printer shutdown
event, and remove support for CLEAR_SHUTDOWN.  A full mcu reset is

Kevin O'Connor b915a2ad7d delta: Make it clear that a "virtual tower" is created
The delta code calculates a "virtual tower" along the line of
movement.  Rework the variable names and comments to make it clear
that this is occurring.

It is not necessary to pass the start_pos variable to the C code as it
is simple to update the start_pos at the start of each movement.

Kevin O'Connor 79f31238b0 mcu: Don't export the commanded_position variable from mcu_stepper
Now that the kinematic classes call the mcu_stepper with millimeters
and seconds it is no longer necessary for them to directly access the
stepper's position in absolute steps.  Rename
mcu_stepper.commanded_position to mcu_stepper._commanded_pos to make
clear it is not a variable intended to be externally accessed.
