VT: SFP: H264: CVO implementation for Rx side

CVO(Coordination of Video Orientation) implemented for H264.

Support Coordination of Video Orientation (CVO) feature that carried in RTP Header extension.
it parses a device degrees(orientation) in RTP extension that remote sent.
(6.2.3 of 3GPP Release 12 TS 26.114)

Once AAVCAssembler parsed a video degress from RTP(CVO) extension,
A native window will be rotated as per parsed video degress.
