This means we can control the desired sizes of its child slots and ensure they get their desired size (SOverlay clips to its bounds)

+ Removed "Clean View" it was not being used.
+ Removed pinned nodes there was no UI for pinning and pinning in code is not neccessary with no shot filtering.
+ Tracks are now always visible, with shot filtering gone this was only being used to hide empty tracks. If we want this behavior we should just delete tracks when they become empty.
+ Removed caching code which is not neccessary now that visibility is simpler.

- All movie scene capture responsiblities are now encapsulated inside the MovieSceneCapture module. Corresponding logic has been moved out of engine classes.
- Fixed time-step capture is fullly supported on PC and mac, real-time capture is still experimental.
- Matinee now goes through the same MovieSceneCapture module logic as actor animations
- AVIWriter can now be instantiated (used to be a single static w/ globals) to give greater control of capturing.
- This mostly addresses UETOOL-446
