soc/intel/common/reset: Add low battery indicator delay

This commit adds a delay to the `do_low_battery_poweroff()` function,
allowing time for the low battery indicator to be displayed before
powering off. The delay is configurable through the
`PLATFORM_LOW_BATTERY_SHUTDOWN_DELAY_SEC` Kconfig option.

Additionally, a low battery indicator event is logged using `elog`
before the delay.

This functionality is enabled when the
`PLATFORM_HAS_LOW_BATTERY_INDICATOR` Kconfig option is selected.

BUG=b:339673254
TEST=Able to build and boot google/brox.
