Revert "Enables/disables simulcast streams by allocating a bitrate of 0 to the spatial layer."

Browse Source 
This reverts commit 18c4261339dc76b220e7c805e36b4ea6f3dd161d.

Reason for revert: Broke internal tests

Original change's description:
> Enables/disables simulcast streams by allocating a bitrate of 0 to the spatial layer.
> 
> Creates VideoStreams & VideoCodec.simulcastStreams with an active field, and then allocates 0 bitrate to simulcast streams that are inactive. This turns off the encoder for specific simulcast streams.
>
