Remove lock from UlpfecReceiverImpl and replace with a sequence checker.

Also making some more state const.

Instances of this class are currently constructed and used on the
"worker thread" but as part of the work for bug webrtc:11993, the
instances will be moved over to the network thread. Since the
class as is does not require synchronization, that is a good property
to make explicit now and then make sure we maintain it in the
transition.

Bug: webrtc:11993
