If fence is passed in we Poll() to find if we have passed the fence and if so we skip the RHI flush
For the benefit of non parallel APIs we still stall the RHI thread while processing the Map()

This mainly covers the new Pixel Streaming plugin version along with minor changes to other parts of the engine:
* removed multiple copies of FThread as it's now a part of Core
* changes to SlateUser required to fix user input in Pixel Streaming
This wasn't formally reviewed due to the size of Pixel Streaming changes, but was skimmed over by Zack Letters before integration

Fix various issues with stream caching in editor. Including:
1) If you play a sound while stream caching is disabled, then enable stream caching and play it, the sound won't be loaded into the cache because it's already precached with DTYPE_Native or DTYPE_Realtime. This was fixed by invalidating and re-cooking the asset on playback if the stream caching settings were changed since last time we cooked it.
2) Fix for issue where the Force Streaming flag would be set to true for any asset you opened while stream caching is enabled in the editor.
3) Fix for issue where newly imported sounds would not play if stream caching is enabled until you restart the editor.
4) Fix for issue where, if you toggle streaming on an asset, the both streaming and non-streaming versions of the asset would stick around in memory.
