Remove deprecated SetRates/SetRateAllocation from VideoEncoder.

This CL removes two deprecated methods from the VideoEncoder interface:
* int32_t SetRates(uint32_t, uint32_t);
* int32_t SetRateAllocation(const VideoBitrateAllocation&, uint32_t);

These are no longer used, instead the new version must be implemented:
  void SetRates(const RateControlParameters&) = 0;

Migrating is straight forward. For the old SetRates, simple replace:
  int32_t MyEncoder::SetRates(uint32_t bitrate, uint32_t framerate) {
with
  void MyEncoder::SetRates(const RateControlParameters& parameters) {
    uint32_t bitrate = parameters.bitrate.get_sum_kbps();
    uint32_t framerate =
      static_cast<uint32_t>(parameters.framerate_fps + 0.5);

For SetRateAllocation, replace:
  int32_t MyEncoder::SetRateAllocation(
      const VideoBitrateAllocation& allocation,
      uint32_t framerate) {
with
  void MyEncoder::SetRates(const RateControlParameters& parameters) {
    const VideoBitrateAllocation& allocation = parameters.bitrate;
    uint32_t framerate =
      static_cast<uint32_t>(parameters.framerate_fps + 0.5);

Two more things to note:
1. The new method is void. Previously the only use of the return value
   in production code was to log a more or less generic error message.
   Instead, log the actual error from the encoder when it happens,
   then just return.

2. The new method is pure virtual; it must be overriden even in test.

This CL is intended to be landed two weeks after creation, on Thursday
May 9th 2019.
