many programs were calling FThreadStats::StopThread() and FTaskGraphInterfaces::Shutdown() explicitly despite they are called from FEngineLoop::AppExit(). Calling them twice is problematic because FThreadStats::StopThread() expects TaskGraph to be still alive. This didn't cause any visible problems before because FThreadStats::StopThread() wasn't called in AppExit().

Get GIsRequestingExit now by IsEngineRequestingExit()
Set GIsRequestingExit now by RequestEngineExit(const TCHAR* Reason) or RequestEngineExit(const FString& Reason)
NOTE If Reason is 4 or less chars it will generate an ensure to force a reason to exit
The reason behind this change is right now setting GIsRequestingExit to true can cause many things to break mainly early on and with out any sort of log warning we have entered this state. We should wrap this behind a function to allow for proper handling

MAJOR FEATURES & CHANGES
============================
Change 4280523 by Patrick.Boutot
Add option in AjaCustomTimeStep to wait until the frame to be ready. Previously, the frame was there but not yet processed so it was possible that it was not ready by the time we wanted to read it. It won't work with interlaced because the 2 fields are processed at the same time. In interlaced, will get a 30fps behaviour when we actually want a 60fps.
Fix bug that didn't set and reset bIsOwned properly when it was first initialized as not owned.
Change 4280526 by Patrick.Boutot
Add accessor to get the leaf media source or output.
Change 4280624 by Patrick.Boutot
Add timecode acessor to media samples
Change 4280626 by Patrick.Boutot
Rework the timing for AJA Media Player. Previously, we took the timing of the frame. That was a bad idea because if 2 incomings video frames were coming a the same time, you would only show one. Making the buffering system useless.
That affects the Custom Time Step since it was waiting for the interrupt signal and in some behavior we would like the frame to be ready to be used by UE. Same the timecode in the MediaSample because we may not used it to stamps the frame.
