charge_manager: Check extpower after charge port

Some platforms don't have an extpower interrupt and therefore use the
`board_check_extpower` function to determine if extpower is
actually present. Any time the EC changes its charge port selection, we
should re-evaluate the extpower as it likely has now changed.

This commit simply does the above.  Note that the default implementation
of `board_check_extpower` doesn't actually do anything, so this
should be a no-op for most boards.

BUG=b:187965740
BRANCH=dedede
TEST=Build and flash drawcia, verify that "AC on" prints are only
printed when we decide to charge from a port and not just when VBUS is
present
