PSA: webrtc::Transport::SendRtp is changing its interface

[Harald Alvestrand]

As part of the effort to get rid of passing pointer + length around (bugs.webrtc.org/14870), the webrtc::Transport::SendRtp and webrtc::Transport::SendRtcp functions have been updated to take an rtc::ArrayView<const uint8_t> argument.

The tracking bug for this particular removal is bugs.webrtc.org/15410.

The old API will be available at least until September 15, 2024.
