Auxfw sync: Remove dependency on EC sync

Auxfw sync used to be guarded by both VB2_GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC
and VB2_CONTEXT_EC_SYNC_SUPPORTED.  Now that the EC and AUXFW sync are
fully decoupled, there are scenarios where it may make sense to do auxfw
sync independent of EC sync, such as early bringup.
