Add support for automatically calculating the internal step_distance
from new config parameters - rotation_distance, microsteps,
full_steps_per_rotation, and gear_ratio.

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.

Collapse the "homing:move_begin", "homing:move_end", home_prepare(),
and home_finalize() into two new events: "homing:homing_move_begin"
and "homing:homing_move_end". This simplifies the homing code.

Don't obtain the step_distance from the config, instead obtain
step_distance from the instantiated stepper object.

Automatically detect if the stepper has a dedicated enable line. If
it does not, then automatically enable virtual enable support.

Add support for enabling the stepper via the communication channel.
This improves support for boards with a shared enable line.

A print_time of zero may translate to a negative clock on a secondary
micro-controller, which would cause an internal error. Change the
code to pass a real print_time or None if it is not needed.

Only the tmc2208 driver needs special read register translation logic.
Rework the code so a default implementation is available for all the
other drivers.
