sensor: Implement sensor "ACCURACY"
Support the accuracy attribute of the sensor. Since the latest
Redfish spec needs to support the accuracy attribute of the sensor,
extend the configuration file syntax to support the accuracy value,
read the value and publish it to the new D-Bus Accuracy interface.
Also, This function will be synchronized to the dbus sensors repo in
the future.
Tested: Build phosphor-hwmon successfully
eg: The configuration accuracy in power supply is 1
