#fix rely on bHasRelevantPoses=false to skip evaluating poses rather than zero-ing out the blendweight array - that way they are also 'cached' for when the node becomes relevant again given the LOD

Introduces a serial number to FBoneContainer that allows easier refreshing of bone-relative data. Eventually the overall CacheBones path could be superseded with lazy-update systems based on this serial number.

This can cause crashes in certain graph configurations (e.g. when within a state machine, Initialize can be called without a CacheBones call directly afterwards)

+ Attribute structures to UAnimDataModel
* These are sampled/copied into AnimSequence whenever they change
+ Attribute related Notifies and Payloads
+ Controller API and Actions for Attribute related behaviour
+ Type traits (TAttributeTypeTraitsBase) to determine support functionality for user-defined attribute types
+ TAttributeContainer equivalent to TCustomAttributes, used for keeping track of attributes at runtime in a TMap similar fashion
* Has two exported specializations FStack/Heap-AttributeContainer
+ IAttributeBlendOperator interface used for Attribute related operations in Anim graph
* Allows for user-defined blending behaviour for their associated types
+ TAttributeBlendOperator providing out-of-the-box blending behaviour for user-defined types
+ FAttributeBlendData helper structure, this encapsulates and abstracts the blend / attribute operations
* Exposes two iterators, allowing BlendOperator to loop through (type) overlapping Attributes and unique attributes
+ Float/Integer/String Animation Attribute structures used to support legacy TVariant CustomAttribute data types
+ Transform animation attribute structure to add support for single-FTransform based attributes
+ FAnimationAttributeIdentifier identifier used to reference an attribute in a script-friendly manor
+ AttributeTypes static API for registering Attribute types
+ FAttributeCurve providing a curve-type with an Attribute type as its underlying key-value
+ TWrappedAttribute helper structure to wrap end template operate on raw memory (TArray buffer)
+ Added tests for
* Attribute related controller functionality and actions
* Attribute curve key reduction
* Evaluating attributes from AnimSequence
* Attribute operations (blend, accumulate etc)
* Functional testing for blendspace attribute evaluation and blending
* Changed default attribute blend type to Blend vs Override
* Updated FBX import/export paths to handle and use new Attribute data structures
* Attribute data is now incorporated into animation source data DDC key
* Deprecated Custom Attributes stored on AnimSequence get converted into their equivalent Attribute structures
* Deprecated all previous CustomAttribute structures, APIs and files
* Corrected some comments in UAnimDataController.h
* Updated existing custom attribute tests to adhere to new blend expectations/behaviour
* Updated AnimSequence resize tests to also incorporate an attribute curve
* Changed layered bone blend to use .5 blend weight vs 1.0 to cover more behaviour
* Added transform attribute used to compare against bone transform during pre-existing functional testing (blended only)
- Deleted CustomAttributes details customization

-Added option to blend profile picker for blend mask creation.
-Fixed issue w/ Blend profile picker sometimes showing in non-standalone mode outside of skeleton editor.
-Fixed issue w/ reset to default w/ blend profiles.
-Added blend mask mode to layered blend per bone node

A collection of major and minor optimizations to anim instance initialization.
Major:
- Added defered root node init. When an anim instance is set to init to refpose, this defers the first call to initialize the blend tree until just before the first Update() call, on a worker thread.
- Skip ConditionallyCacheBonesForState in state machines in the case where we would call CacheBones_AnyThread during first Initialize_AnyThread. This avoids duplicate work being done, as graph traversal counters will let through sychronization calls if they have yet to be updated (ie. their count is INDEX_NONE).
- Cache access to nodes that need pre-update, dynamic reset, one-time initialization, as well as state machines in the generated class to avoid iterating all anim nodes on initialization.
Minor:
- Cache access to node properties when re-linking nodes to avoid duplicate memory round-trips.
- Cache access to LUT size in FBaseBlendedCurve::GetValidElementCount, avoiding duplicate memory round-trips.
- Prevent FName rehashing from string (intended to strip whitespace) when initializing FBoneReferences.
- Cache access to AnimCurveMapping smart name container on USkeleton, preventing a TMap lookup every time we access the smart name container.
- USkeleton::GetCurveMetaData now uses a 'fast path' when accessing using smart name UID. In this case we can avoid the TMap lookup as the UID is always a direct index to metadata at runtime (slow path still applies in editor builds).
- Avoid calling FAnimNode_LayeredBoneBlend::ReinitializeBoneBlendWeights in Initialize_AnyThread, as CacheBones_AnyThread will be called straight after anyways.
- Cache access to curve UID count and LinkedBones array in FAnimNode_LayeredBoneBlend::ReinitializeBoneBlendWeights, avoiding duplicate memory round-trips.
Upgrade notes:
- Breaking change! Custom anim nodes that implement OnInitializeAnimInstance now need to return true for the new accessor NeedsOnInitializeAnimInstance to be called at init time.
- The meaning of HasPreUpdate and NeedsDynamicReset has changed slightly. Previously these were called at init time, so if their results were mutable it was possible to re-init an anim instance with new settings. Now they are called at CDO load time this is no longer possible.

Useful for fixing scaling issues arising from "Layered blend per bone" node. For example, when blending lower body locomotion with upper body aiming and feathering the lower body weight up the spine, scaling on the spine can propogate through the skeleton to the hands causing them to drift from the weapon. This removes the need to manually fixup the spine's scale after blending the poses.
BlendMeshPosesPerBoneWeights and BlendLocalPosesPerBoneWeights are now folded into a single function: BlendPosesPerBoneFilter.

Poses & curves are now moved instead of copied where possible.
Also removed needless passing of bone space transforms to UAnimInstance::ParallelEvaluateAnimation, which further removes an extra allocation for sub-instances.
