Move the enable line tracking out of the main stepper.py code. This
simplifies the main kinematic code.

Directly disable all the stepper motors on a global motor_off() from
the StepperEnable() class in stepper_enable.py. This simplifies the
toolhead and kinematic classes.

Minor rework of the loop to reduce the chance that numerical stability
could cause an infinite loop.

Update BLTouch.md, FAQ.md, and sample-probe-as-z-endstop.cfg to
recommend using a safe_z_home config section over a homing_override
config section.

No longer allow the primary extruder to be named "extruder0". This
avoids internal and external confusion between the printer objects and
config section names.

Do not apply max_extrude_cross_section check, and do apply
extrude_only_xxx checks to Z only moves that also extrude. Some
printer start scripts will prime the extruder while moving the Z.

Calculate the ratio of axis distance to total move distance (axis_d /
move_d) and store in a new member variable axes_r. This avoids
needing to recalculate the value in other code.

Only track a single acceleration movement in a 'struct move' instance.
Break the classic trapezoid movement (accel, cruise, decel) into three
separate movements. This simplifies the calculation logic.

Load all items from the look-ahead queue into the trapezoid velocity
queue, and then flush that queue by time. This prevents the host cpu
from being starved on very long moves (which may require a large
number of steps to be generated). It also improves the overall
performance.
With the batch flushing logic in place, it is no longer necessary to
split homing moves up.

Now that all callers use the trapq system to queue moves, it is no
longer necessary to individually allocate and fill a 'struct move'.

Eliminate the old gen_steps() call now that all callers have been
converted to the newer trapq based generate_steps().

Now that all kinematics use the trapq system, there is no need to call
into the kinematics on each g-code move.

Support associating a stepper_kinematics with a trapq. Support
generating steps from a time range on the given trapq.

Add support for building a list of moves in the trapq.c code. Update
the toolhead code so that moves generated from the look-ahead code are
added to that list.

If the kinematic position calculation function had an error in it (if
it produces sudden position changes) then it could lead to an infinite
loop in itersolve_gen_steps().

Break up the connect phase into two phases - mcu_identify and connect.
The first phase will contact all the micro-controllers and obtain the
"identify" data dictionaries for them. Once all the micro-controllers
have been contacted, then they can be configured. This fixes an issue
with FIRMWARE_RESTART not working correctly on multi-mcu setups that
use restart_method=command.

Add to printers.test test case. Don't disable the
max_extrude_cross_section check by default (users should verify they
want that safety feature off).

Wait in the M25 command handler until the work_handler() background
timer fully exits. This ensures that subsequent g-code commands (such
as M27 or M24) will correctly report a paused state.
