Reland "Propagate media transport to media channel."
This reverts commit 37cf2455a420124b341ad06ac27fa3c4dbd29d3c.
Reason for revert: <INSERT REASONING HERE>
Original change's description:
> Revert "Propagate media transport to media channel."
>
> This reverts commit 8c16f745ab92cb6d305283e87fa8a661ae500ce4.
>
> Reason for revert: Breaks downstream project
>
> Original change's description:
> > Propagate media transport to media channel.
> >
> > 1. Pass media transport factory to JSEP transport controller.
> > 2. Pass media transport to voice media channel.
> > 3. Add basic unit test that make sure if peer connection is created with media transport, it is propagated to voice media channel.
