basecmd: Generalize the "move queue" runtime storage

Detect the maximum size of each "move queue" item during the
configuration phase instead of using the stepper move struct.  This
allows the stepper code to be contained entirely in stepper.c and it
allows for future run time allocations from other types of objects.
