[Overuse] Make VideoStreamAdapter responsible for executing adaptation.

This CL moves GetAdaptUpTarget(), GetAdaptDownTarget() and
ApplyAdaptationTarget() - and related code - to the VideoStreamAdapter.

This includes pieces related to calculating how to adapt, including:
- DegradationPreference
- BalancedDegradationPreference
- AdaptationRequest and last_adaptation_request_
- CanAdaptUpResolution()

The VideoStreamAdapter's interface has changed: VideoSourceRestrictor
methods are now hidden in favor of methods exposing AdaptationTarget.

This CL also does some misc moves:
- GetEncoderBitrateLimits is moved and renamed to
  VideoEncoder::EncoderInfo::GetEncoderBitrateLimitsForResolution.
- EncoderSettings moved to a separate file.

// For api/video_codecs/video_encoder.[cc/h] changes, which is the
// moving of a function.
