Add wakeup alarm anomaly detector

Browse Source 
Wakeup alarm count frequent is calculated by a / b, where
1. a: the total wakeup alarm count since the last full charge
2. b: total time running since last full charge
(include sleeping time)

This cl also has the following changes:
1. Move bunch of methods to BatteryUtils
2. Create type WAKEUP_ALARM
3. Add and update tests

Upcoming cl will make sure we get the threshold from
AnomalyDetectionPolicy

Bug: 36921529
Test: RunSettingsRoboTests
