UE4 - rollup of many performance changes
* increased max threads for task graph and added a way to reduce task threads at runtime for testing the optimal number
* added a way to track excessive allocation at runtime without using the memory profiler: LogGameThreadMallocChurn.Enable
* ps4: fixed a few problems with the platform properties, IsRunningGame was returning false
* added inline storage for one delegate in multicast delegates
* fixed excessive allocation on the script stack traceback
* fixed excessive malloc calls throughout the animation system
* added stats throughout the animation system
* reworked parallel queue ticks
* fixed excessive malloc calls in cloth and physics animation systems
* fixed GHitchThresholdCVar
* minor improvements to abtest
* added ability to change thread affinities on the fly so they can be tuned
* cvars to control animrate optimization and spew the results: EnableAnimRateOptimization, SpewAnimRateOptimization, DrawAnimRateOptimization, ForceAnimRate
* optimized malloc calls in cascade and gpu particles
* optimized malloc calls in input system
* removed visual logging and ability log from consoles and fixed a few compile errors related to doing that
* optimized gameplaytags
* added a few cvars to cause stalls in various parts of the pipeline to identify critical paths and bottlenecks: CriticalPathStall.*
* added console command to toggle all known outstanding perf tweaks: Orion.SetupPerfCVars

- One driver value can now drive multiple components
- How a component is driven is now configurable (add to input, replace, add to ref pose and replace)
- The range limit is now defined on the input (before the multiplier is applied) rather than the output (existing ranges are fixed up on load)
- New details customization to make working with the node easier
- Individual scale components can now be a driver or one of the driven components, rather than just the max component of scale
- The node title now displays the driving equation (e.g., driven.rotation.z = -0.5 * driver.rotation.x)
Animation: Added a custom version for AnimGraph/AnimGraphRuntime usage
Upgrade Note: The exact behavior of the original node was not preserved, but there are now more configuration options, so please revisit any uses of bone driven controllers in your animation blueprints

- Added support for using a curve to map from input range to output range
- Added compilation warnings when a bone or component still needs to be selected
- Added a customization to hide the range/multipler when using a curve, and gated editing of the range based on bUseRange
- Minor optimization to evaluation speed
- Reorganized the properties into logical groups (Source/Driver, Mapping, Destination/Driven)
[CL 2591125 by Michael Noland in Main branch]
- Moved all skeletal control nodes to start out
Upgrade Note: Modules containing custom animation nodes will need to have a dependency on the new "AnimGraphRuntime" module added to their Build.cs file
