Some stepper motor drivers do not respond well to rapid "step +
direction change + step" events. In particular, it is believed this
can cause "over current" events on the tmc2208 drivers when they are
in "stealthchop" mode. Detect these events and remove them from the
generated step times.

It is likely only developers will be interested in testing the menu
system, so no need to have it in the default menu.

Disable support for customizing the main lcd display content via the
menu system. Advise users to use the new display_data config sections
as a replacement.

Introduce a new config based system for specifying the on-screen
contents of an lcd screen. The default screen configuration (found in
klippy/extras/display/display.cfg) is the same as the previous
hard-coded display, so this should not change behavior for existing
users.

If the stepper changes direction then the average velocity since the
last step pulse isn't a good indicator of the next step pulse.
Instead, reset the bounds checking to use a low starting guess.

The queue_append system predates the iterative solver - it was useful
when many different kinematic functions directly added steps to the
step compression queues. With the iterative solver being the only
source of step generation, it is simpler to directly add steps from
the iterative solver code.

Use new mcu.lookup_query_command() for all commands that query
information from the micro-controller.

Convert standard queries to use the acknowledgments of the sent
command to determine if the response was received or not. This also
controls command retransmissions (should the response have been lost).
The tmc_uart.py will continue to use the old mechanism as the tmcuart
responses are not sent synchronously with the query command.

Add ability for the host code to get a notification when the ack for a
command sent to the micro-controller is received. This is in
preparation for improved detection of message loss between mcu and
host.

It's not valid to set the TPWMTHRS in a "klippy:connect" event handler
because the TMCVirtualPinHelper and TMCCommandHelper classes were
expecting that field to be set during the config reading phase.

Change home_wait() to return if the homing operation completed
succesfully or not. This simplifies the callers.

Update the endstop code to return its trigger completion object during
home_start(). Update the toolhead class to take a completion object
(instead of creating its own). This reduces the number of
intermediate callbacks needed during a homing operation.

It's simpler to query the "printing" status from the idle_timeout
module on an event than it is to track changes to the printing status.
