powerstats: Introduce AoC timed data provider

Browse source 
Reading data from an AoC sysfs node by getline takes 1 second. In total
there are 17 AoC sysfs nodes that must be read. The worst case is taking
17 seconds long that is greater than dumpsys timeout. Therefore, we need
the timeout mechanism to ignore the AoC power stats reporting when AoC
latency exceeds the allowed time.

Bug: 219630658
Test: dumpsys android.hardware.power.stats.IPowerStats/default
