AP_InertialSensor: on accel cal failure don't save values to zero
...
When the accel calibration fails leave the previous values saved but set them to defaults (scale default is ones, not zeros) and notify the GCS
This fixes an arithmetic exception when doing a second accel cal after the first one failed

AP_InertialSensor: added INS_FAST_SAMPLE parameter
...
this allows enable/disable of fast sampling per IMU, making
experimentation easier.
It also fixes the fast sampling to always average over 8 samples, and
fixes the 9250 to use the correct accumulator when not doing fast
sampling

AP_InertialSensor: catch FIFO alignment errors using temperature reading
...
Two cases of what seems to be FIFO alignment errors have been seen on
a Pixracer-beta board with a ICM-20608. At a cost of 2 extra bytes per
transfer we can catch these by looking for sudden temperature changes
caused by bad data in the temperature registers.

store the driver version. When changing the driver behavior in
non-compatible ways, changing this version will trigger a request for
calibration.

AP_InertialSensor: save id for gyro and accel instances
...
This allows each sensor to be uniquely identified in the system by using
either the index inside the backend or for those that use the Device
interface, to use the bus type, location, and device id.
We leave 16-bit for each sensor to be able to change its own
identification in future, which allows them to be changed in an
incompatible manner forcing a re-calibration.

AP_InertialSensor: save only gyro calibration
...
When we are initializing the gyro and then saving the calibration we are
also saving the calibration values for the accelerometers. Right now
this is non-problematic, but we want to check that the ID of the
accelerometer corresponds to the ID of the sensor detected. If we also
save accel calibrations we would actually override the ID of the
accelerometer.
Rename the method to _save_gyro_calibration() and save only on gyro
values.
