EC software sync: Split up EC and auxfw sync
Currently, the logic for updating auxfw is entangled with the logic
for performing EC software sync. This patch attempts to split them
apart, so that they can be used separately. VbSelectAndLoadKernel()
currently still performs both, EC first and then auxfw. The intended
use-case for this functionality is to perform EC software sync only in
coreboot's romstage. Unit tests were updated to ensure functionality
is effectively unchanged.
