Change the default CANbus frequency from 500000 to 1000000. A higher
frequency allows for greater data transfer rates, lower latency of
messages, and should overall be more robust.

The stalled_bytes counter refers to the number of bytes that are not
yet eligible for transmission. However, the naming leads to confusion
as it could be interpretted as an inability to transmit data. Rename
to upcoming_bytes to try to avoid that confusion.

Previously, the globalscaler was calculated during the config parsing and set to a fixed value. If the current was changed for any reason after the initialization, only IRUN and IHOLD would be changed. This however caused issues:
- If the new current was lower, then the resolution of the possible current values would be low since there are only 32 IRUN/IHOLD steps.
- If the new current was higher, it wouldn't actually work since IRUN and IHOLD are capped at 31, so it wouldn't be possible to increase the current without increasing globalscaler.
With this commit, the globalscaler is recalculated whenever necessary in order to ensure the correct range of IRUN/IHOLD is used.

After a G28 z-axis homing, there is a final z hop.
It was hoping to height z_hop as an absolute z height rather than relative.
If the z-axis home leaves the head at a z height higher than z_hop,
e.g. because you were using a probe to do z homing,
this meant that it was z hopping in the negative z direction, which
could result in crashing the toolhead.

It is preferable to program the tmc drivers with an irun (or cs)
setting near 31, as otherwise the driver may have reduced microstep
precision. It was possible for the driver to be programmed with
irun=16 or irun=17 when it could have been configured with irun=31
with vsense=1 instead. This would occur on tmc2130/tmc2208/tmc2209
drivers for values around 0.900 to 1.000 amps (when using a typical
sense_resistor settings of 0.110 Ohms).
Change the code to prefer using vsense=1 to avoid this issue.

Commit 689231df changed the default step_pulse_duration to 100ns for
TMC drivers that are configured in UART/SPI mode, but it failed to
document that change in Config_Changes.md and Config_Reference.md.
Update those documents to reflect that change.
Update the code so that a user may specify a custom
step_pulse_duration even on TMC drivers that are configured in
UART/SPI mode. This may be useful for drivers that use a level
shifter on the step pin that requires more than a ~300ns to detect a
level change.

It seems the common "beta 3950" thermistors generally follow a
temperature table defined by the new "Generic 3950" definition. Using
a table that actually follows the "beta 3950" temperature curve is
generally less accurate. Deprecate the existing "NTC 100K beta 3950"
definition to avoid this common issue.

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.

A larger smooth_time results in a slower reaction time for the PID.
This increased delay can cause temperature oscillations with high
power heaters. Many boards produce good results without any
smoothing. So, it seems a smooth_time of 1 second is a better
default.
