Instead of crashing with a CHECK fail when an insertable stream of a
Video RTPSender is given a frame from an RTPReceiver's insertable
stream, construct a reasonable analogous sender frame and pass it
through to be decoded.
A small step towards removing the split we have between Sender and
Receiver implementations of TransformableFrameInterface which just
confuses users of the API.
Counterpart to https://webrtc-review.googlesource.com/c/src/+/301181 in
the opposite direction.
