Vincent Politzer cabbfcfd7e fix: Use HalPowerManager for battery percentage (#1005)
## Summary

The introduction of `HalGPIO` moved the `BatteryMonitor battery` object
into the member function `HalGPIO::getBatteryPercentage()`.

Then, with the introduction of `HalPowerManager`, this function was
moved to `HalPowerManager::getBatteryPercentage()`.

However, the original `BatteryMonitor battery` object is still utilized
by themes for displaying the battery percentage.

This PR replaces these deprecated uses of `BatteryMonitor battery` with
the new `HalPowerManager::getBatteryPercentage()` function.
