mb/google/bluey: Disable charging during normal boot

Browse source 
This commit adds a call to disable_slow_battery_charging() in the
lb_add_boot_mode function.

The logic ensures that charging is disabled if the system is booting in
a normal mode, where neither the LB_BOOT_MODE_LOW_BATTERY nor
LB_BOOT_MODE_OFFMODE_CHARGING flags are set.

This prevents unintended charging by the AP firmware when the device
is not in a low-battery state or booting from off-mode charging to
avoid battery unmanaged health related problem.

TEST=Able to build and boot google/quenbi.
