Revert "VP9 encoder: handle disabled layers correctly"

This reverts commit 88fe84b7fbcb8dffe07b98d21d8a11572259c0d0.

Reason for revert: Downstream project isn't updated to the latest libvpx roll yet, thus some tests are broken.

Original change's description:
> VP9 encoder: handle disabled layers correctly
> 
> Now vp9 screenshare would enable new layers as soon as requested and will
> force all spatial layers present on the next frame, even if they should be
> dropped because of frame-rate limiting.
> 
> This might cause frame-rate liming to be exceeded if layer is toggling on
> and off very often, but this situation is bad itself. E.g. in realtime video
> it will cause too many key-frames.
> 
> Now SvcRateAllocator and VP9EncoderImpl are aware that there may be some skipped
> layers before the first enabled. Key-frames and ss_info triggering logic is also
> updated.
