common:online_calibration: Spoof sensor data

This change allows the `accelspoof` ec command to also
override the calibration data (bypassing the calibration
module). This config flag should be used when testing
layers above the EC (kernel and up)'s handling of the
calibration values.

BRANCH=none
BUG=none
TEST=Built on eve and added unit tests.
TEST=make run-online_calibration_spoof -j
