rwsig: add host command for controlling rwsig task
Add new host command EC_CMD_RWSIG_ACTION for controlling rwsig task.
This allow us to make firmware stay at RO without toggling reset pin.
flashrom can use this host command and removed the need to use any
out-of-band pin to toggle the reset pin (and make RWSIG stay in RO).
BRANCH=none
BUG=b:37584134
TEST=on eve, `ectool --name=cros_tp rwsigaction abort` should prevent EC
from jumpping to RW after RWSIG check.
