Henrik Boström f08e2663aa Delete kAlwaysAllowPayloadTypeDemuxingFieldTrialName flag.
This flag was used as a kill switch in case turning off payload type
demuxing in some Unified Plan cases (https://crbug.com/webrtc/12814)
would cause any issues. That landed way back in M93 and no issues were
ever reported, so time to clean up the flag.
