It is not valid to call time.sleep() in the host python code (it could
causes glitches in other processing, and it does not ensure there is a
pause between operations on the mcu).
Use minclock instead of time.sleep() to ensure there is a sufficient
pause during chip startup.

Previously, the BatchBulkHelper class was designed primarily to
register webhook clients, and internal clients used a wrapper class
that emulated a webhooks client.
Change BatchBulkHelper to support regular internal callbacks, and
introduce a new BatchWebhooksClient class that can translate these
internal callback to webhooks client messages.
This makes it easier to register internal clients that can process the
bulk messages every batch interval.

The APIDumpHelper class is mainly intended to help process messages in
batches. Rework the class methods to make that more clear.

The APIDumpHelper class already ensures that the start/stop callbacks
will only be called when needed.

All the accelerometers use a standard response for their query_status
messages. Create a common helper class to process those responses.

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
Stress tested for 23hrs with two MPU-6500 attached to one I2C bus on RPi
and one on a ATmega328P (Seeduino Nano)

Calling python functions can have high overhead. Inline the
twos_complement code in the _extract_samples() inner loop.

The MPU9250CommandHelper() class is nearly a duplicate of
ADXL345CommandHelper(). Rename ADXL345QueryHelper() to
AccelCommandHelper and remove user facing references to "adxl345". Use
it directly from mpu9250.py .
