refactor: Deduplicate battery drawing code and fix Lyra charging indicator (#1437)

Browse Source 
## Summary

**What is the goal of this PR?**

Following up on #1427:
- Extracted shared battery drawing logic, including lightning bolt, to
reduce duplication.
- In Lyra with segmented battery the lightning bolt was hard to see, so
when charging Lyra now uses a solid battery fill.
