Reland "Modify Bundle logic to not add & destroy extra transport at add-track"

This relands commit I41cae74605fecf454900a958776b95607ccf3745, after
reverting it in order to merge the revert to M93 (the deadline for
which is now exceeded).

Original change description:

> If a bundle is established, then per JSEP, the offerer is required to
> include the new track in the bundle, and per BUNDLE, the answerer has
> to either accept the track as part of the bundle or reject the track;
> it cannot move it out of the group. So we will never need the transport.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See here for instructions on how to get started developing with the native code.
