Add producerId so we know when the BBQ producer has been changed.
If BBQ producer changes but the SC remains the same, the frame numbers
for the SC will get reset. This causes issues if there's a barrier layer
set because the barrier is waiting for a particular frame number before
applying the transaction. Since the frame numbers have been reset, the
barrier will be greater than the incoming frame numbers. The change adds
a producerId to the buffer being sent so it can check if the producerId
is older than what's currently set on the Layer. If there's a barriers
set from the old producer, the buffer can be released and not applied
and will stop SF from waiting indefinitely.
