The set_register() code may block, and it therefore may be possible
that the loop in _init_registers() could occur in parallel with other
updates. That could result in a "OrderedDict mutated during
iteration" error.
Avoid the error by querying the latest value during each iteration of
the loop.

It's possible to build and configure tmc5160 drivers with external
mosfets that support more than 3 amps. The actual maximum for tmc5160
drivers is dependent on how the board is wired and the mosfets used.
Increase the error check to 10 amps. This error checking is primarily
intended to catch "obvious misconfigurations" (eg, specifying
milli-amps instead of amps), and the new value of 10 amps should
suffice for this task.

The output_pin module is only capable of updating an output pin at
most once every 100ms. Add a new pwm_tool module that is capable of
queuing updates in the micro-controller and thus allowing for much
higher update rates.

This reverts commit 6749985302.
A defect was found in the above commit (the input shaper code calls
note_step_generateion_scan_time() for many steppers, so the
input_shaper class can't be used as the index).

Limit the maximum temperature in MAX31865.calc_adc() to the melting
point of platinum. Above this temperature the Callendar-Van Dusem
formula does not make sense. The default value for max_temp is
99999999.9 and at this temperature the result of this formula is
negative. This sets max_sample_value to 0 which causes the mcu
to shutdown.
Set max adc value to (1<<15)-1 . This is needed because the max value of the adc register
of the MAX31865 is 0b1111 1111 1111 1110 which represents
32767 and not 32768.

The relative_reference_index will now refer to a coordinate that is
static and cannot be changed at runtime. If new mesh parameters
are specifed and the reference lies outside of the mesh then the
reference location will be probed.
Additionally this introduces a 'zero_reference_position' option which
accepts a specific X/Y coordinate. This may be used in place of the
relative_reference_index.

When mesh parameters change the substituted indices need to be
updated, even when using the default point set. Always generate
new points to perform this update rather than cache
the "orig_points".

The control bytes for the AHT20 and AHT21 are identical to the AHT10, but I had not been able to test just yet to ensure the sensor code supported the other sensors. I've wrapped up testing and updated the comments/docs to reflect this additional support.

Fixes common MPU-9250 accelerometer issues for RPi Linux MCU and
improves reliability on all other architectures by adjusting the MPU-*
reading algorithm to only read whole Klipper messages' worth of
data from MPU-* and eliminating many unnecessary checks of the MPU FIFO
fill-level that consumed bus bandwidth needed for data transfer. Fixes
intermittent "Lost communication with MCU 'rpi'" due to "Timer too
close" and transposed / corrupted data due to FIFO overrun/data loss
when using MPU-* accelerometers. In addition FIFO overrun checks are
performed by testing the MPU interrupt flag vs. inferring from the FIFO
fill level.
Stress tested for 13hrs with two MPU-6500 attached to one I2C bus on RPi
and one on a PR2040

This commit adds support for the I2C-based AHT10 ambient temperature sensor. The sensor comes pre-calibrated and has a fairly simple command interface, so the interface class is in-turn relatively simple. So far this has been tested on a BTT GTR 1.0 MCU board (STM32F4), and seems to work fine.

Implement a helper for calculating velocity based thresholds for tmc drivers. This code was written in such a way that it can be used with more fields than just tpwmthrs.

If tcoolthrs is configured (not the default 0), then do not force
the value of tcoolthrs=0xfffff during homing. This way, tcoolthrs
can be set to a custom value during homing.
`tpwmthrs` and `en_pwm_mode`/`en_spreadcycle` are now also
correctly restored if they were changed after startup.

`multistep_filt` was not configured at all on tmc2240 and tmc5160. As such, it would default to the value of 0 when the GCONF field was sent to the driver. However, that field has a default value of 1 in the driver, so klipper was overriding the defaults by accident.
This field improves the stability of velocity based thresholds (it's effectively TSTEP filtering) and it also improves the current regulation stability in stealthchop2 (according to the datasheet).
This field was already set to 1 correctly in the tmc2208/tmc2209 driver code.

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.
