webrtcsink: trigger negotiation manually
...
We no longer connect to on-negotiation-needed, this in order to call the
consumer-added signal without holding the state lock:
Going to Ready triggers synchronous emission of the on-negotiation-needed
signal, during which time the application may add a data channel, causing
renegotiation, which we do not support at this time.
This is completely safe, as we know that at that point all conditions are
gathered: webrtcbin is in the Ready state, and all its transceivers have
codec_preferences.

change x264enc default bitrate to match nvh264enc
...
Assume default bitrate should be the same for a given codec (here, H264 is 2048u32) regardless of which encoder is used (x264enc, nvh264enc).

webrtcsink: Initial congestion control implementation

Naive heuristic lifted from an earlier proof of concept,
augmented with logic from
https://datatracker.ietf.org/doc/html/draft-ietf-rmcat-gcc-02#section-5.5
A property is exposed to disable congestion control for
testing purposes, it can be extended in the future to allow
selecting a different congestion control scheme.
