Cast Extensions API: Major namespace and object renaming

There is no functional change in this patch. This change only does
renaming.

Extensions API namespaces:
webrtc.castSendTransport -> cast.streaming.rtpStream
webrtc.castUdpTransport -> cast.streaming.udpTransport

Class renaming:
WebRtcNativeHandler -> CastStreamingNativeHandler
CastSendTransport -> CastRtpStream

Tests and related files are also renamed to get rid of the webrtc
label.

BUG=301920
