venus: check and configure new ringMonitoring feature

At ring creation, if supported by renderer, we can request
ringMonitoring. During driver ring waits, the ring's new ALIVE status
bit will be checked periodically at the configured rate. If the bit is
not set, the renderer must have crashed and the driver should do the
same to signal a problem to the app/user.
