Refactor player sessions
Fix PixelStreamingAudioComponent had delayed audio.
Fix audio bitrate from Unreal Engine to browser was set to a low default causing compressed audio quality in stream. The new default is now Opus maximum value of 510kb/s.
Fix the Selective Forwarding Unit (SFU) not being added to the Pixel Streaming samples folder for a packaged project
Fix default max bitrate not being high enough to support 4k.
Fix reconnections not autoplaying in the browser.
Add datachannel support to SFU.
Add WebRTC c++ client behaviour to pixel streaming system. This is used for developing unit tests.
Add a unit test that will start streaming, connect a client and check that a data channel message can be sent.
Add the ability for a user to start/stop streaming as needed through the use of PixelStreaming.StartStreaming and PixelStreaming.StopStreaming
Add the ability for the stream resolution to be changed at runtime
Notes: AVEncoder no longer stores a width and height; These properties have been moved to the FVideoEncoderInput. This input is now the source of truth and both AMF and NVENC will adapt their resolution to the input resolution.

This resolves bitrate issues in WebRTC caused by inconsistent frame rates.
These changes are intended for 5.0 and licencees who are using source builds of the engine to get the updates before 5.0 is released.
