Data driven condition bindings
Authoring and compilation of the new type is hidden behind a project setting.
Fix crash when changing hooked event and trying to edit conversion function parameters.
Fix issue with events valid source check node being purged from the graph upon regenerating connections in the wrapper graph.
Fixes FORT-768257
#tests Tested in editor and in game. Tried with widget property bindings, tried with vm bindings. Verified with multiple bindings to ensure we only execute when it's the condition property that is modified. Ran with cooked version. Tested in standalone and pie.

The temporary array holding the generated graphs should not be affected by undo because it holds data created on the compiler context which is itself not transactional.

This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

- Any code causing a linker mismatch needs to explicitly clear loading flags for their object to avoid asserting. This is to make the intention clear that rename will make loading correctly impossible when moving the object to a different linker unintentionally. So either clear the loading flags of the object (i.e. finish loading via load calls such as ConditionalPostLoad) or forcibly allow mismatching via the new flag.
- When marking an export as invalid in FLinkerLoad::InvalidateExport() we now also clear loading flags since it is wasteful to load invalid objects.
- Exports marked as invalid are no longer reset to be valid when the linker is reset for the object instance. This is to prevent reloading invalid objects when re-using a linker already resident in memory if a subsequent package load is requested.
- When UStruct upgrades UFields to FFields, the UStruct objects are marked as invalid to prevent reloading the objects unnecessarily
- Fixes an issue where since Rename can clear the linker for mismatched types, any calls to FLinkerLoad::InvalidateExport needs to be moved before the rename operation to be effective.
- CollectUnreachableObjects will no longer mark unreachable objects as invalid in the linkerloader. That code would mark objects as invalid until the linker is destroyed which incorrectly assumed would happen soon. If however a load for the same package occurs before the linker is destroyed, the in-memory linker would be re-used keeping the marked exports as invalid so those exports would not be loaded (even though they should have been).

[RN] UObject::Rename will always remove the renamed object's linker if the rename moves the object into a different package. As a result, any renames occuring while an object is loading will now assert instead of leading to hard to diagnose crashes long after the Rename call has completed. If renaming to a different package is intentional and the linker should not be cleared, the new flag REN_AllowPackageLinkerMismatch can be used to prevent clearing linkers on the object even though the linker is for a different package than the package has been renamed to be part of.

Change the category of MVVMDeveloperProjectSettings.
Fix bug in customization, the bCreateSetter flag was set but never propagated to the copied object.

MVVM: Enable compilation warning when there are 2 bindings trying to change the same value. Since the order is not configurable that can lead to binding executing in different orders and do run in an unexpected behavior.
