Remove RecordingState::keyframe_needed.

Browse Source 
This variable is not used, always set to false but complicates
things for `keyframe_generation_requested_` as setting keyframe_needed
requires keyframe_generation_requested_ to be read synchronously from
what soon will be a different thread than where SetAndGetRecordingState
is called on.
