pacman: Fix bipolar single measurements
Currently single shot measurements assume that the values read from the
pac sensors are unsigned integers. However, in bipolar modes these
values are signed integers which results in incorrect values reported.
This commit updates the functions used to measure voltage, power, and
current in single shot to work with signed integers in bipolar mode.
BUG=b:244319844
TEST=Ran on skyrim device, verified that bipolar single shot
measurements report correct values
