stepper: Make step pulse duration customizable at run-time

Browse source 
Remove the STEP_DELAY Kconfig option and replace it with a per-stepper
step_pulse_duration printer.cfg config option.

The AVR code will continue to have optimized code to step and "unstep"
in the same function (which is automatically activated when the step
delay is 40 ticks or less).  This change removes the Kconfig option
for single function step/unstep on 32bit processors.

## Changes
20211104: The "step pulse duration" option in "make menuconfig" has
been removed. A new `step_pulse_duration` setting in the
[stepper config section](Config_Reference.md#stepper) should be set
for all steppers that need a custom pulse duration.
20211102: Several deprecated features have been removed. The stepper
`step_distance` option has been removed (deprecated on 20201222). The
`rpi_temperature` sensor alias has been removed (deprecated on
