[ACR-1598] Add new APIs for set param maximum lateness and RTP latency

- MEDIA_STREAMER_PARAM_SINK_MAX_LATENESS
- Video frame drop occurs when the PTS(presentation time stamp) of segment received as RTP streaming
  exceeds the boundary of the base clock.
- If the frame is later than max-lateness, the sink will drop the buffer without calling the render method.

- MEDIA_STREAMER_RARAM_RTP_LATENCY
- Default amount of ms to buffer in the jitterbuffer of RTPbin

- Minor change
  1) Add audio clock rate for OPUS
  2) Change Default Video RTP format from VP8 to H264

[Version] 0.1.119
