Allocate the low-level C stepcompress object in the motion_queuing
module. This simplifies the mcu.py code as it no longer needs to
track the stepqueues for the steppersync object.

Add an allocate_trapq() helper function to facilitate the creation of
a low-level C trapq object. Track all trapq objects and clear history
on them globally when the main motion queues are flushed.

Create a new module to assist with host management of motion queues.
Register all MCU_stepper objects with this module and use the module
for step generation.
All steppers will now automatically generate steps whenever
toolhead._advance_flush_time() is invoked. It is no longer necessary
for callers to individually call stepper.generate_steps().
