chgstv2: Make board_critical_shutdown_check specify action on critical soc
Currently, board_critical_shutdown_check is used only in the context
of CONFIG_BATTERY_CRITICAL_SHUTDOWN_CUT_OFF. It returns true to cutoff
the battery or false to take no action.
This patch extends board_critical_shutdown_check to allow it to control
what actions to take on critical battery condition.
With this change, each board can also customize critical battery actions
with more granularity (per OEM, BOARD_VERSION, etc.).

BRANCH=nami
TEST=Verify a battery is cutoff at critical low charge on Scarlet and
DUT wakes up by AC plugin on cros/firmware-scarlet-10388.B.
