Update detectSettingsAnomaly API to detectPowerAnomaly(1/2)

Since the detectSettingsAnomaly method does not only detect settings but
also other power related anomalies. Change the method name to
detectPowerAnomaly to make it more reflects what it really does.

Bug: 320404576
Test: make SettingsGoogleRoboTests
