Currently, the system does not explicitly distinguish between a low
battery boot with a charger and one without. This is critical for
deciding whether to allow the boot to proceed or to protect the
battery.
This patch:
1. Re-introduces LB_BOOT_MODE_LOW_BATTERY to represent a critical
battery state without a charger present.
2. Refactors set_boot_mode() to accommodate off-mode charging and
evaluating battery health (low-batter w/ or w/o charger present)..
TEST=Verified on Bluey:
- Boot with charger + low battery enters LOW_BATTERY_CHARGING.
- Boot without charger + low battery enters LOW_BATTERY..
- Boot with normal battery enters NORMAL mode.
