Scoring weights can now be specified at several levels of abstraction.
Channel: Pose weight vs trajectory weight.
Horizon: History weight vs prediction weight.
Type: Weights per feature types, such as positions and velocities.
Weights are normalized at each of these levels. So ultimately the weights that
make up all channels of a weights group will sum to 1 (or zero if entirely disabled).
Several new concepts were introduced for this system that aren't fully
formalized. Channels aren't a concrete data type, but I'm imagining we'll head
in that direction where a Schema is made up of Channels which themselves contain
sampling paramters like time/distance offsets and what to sample. The weights
system sets itself up in such a way to effectively pretend channels exist.
Similarly, horizons aren't an explicit data type either and the weights system
pretends they sort of are for presenting this high level concept of past vs future
weight to the user.
I have removed the previous weighting system including per sequence weights.
This feature will be replaced by a grouping system for databases in the future.
Groups will be collections of sequences and a set of weights for that group.
This is why the WeightsContext contains an array of 1 group of weights-- it's
setup that way to vector the implementation toward groups.
Speaking of the WeightsContext, the motion matching node holds onto one and
updates it every frame. This is in order to support changing weights at
runtime. There are a set of dynamic weight parameters that can be used to scale
the weights of all weight groups within a database. The WeightsContext tracks
the prior dynamic weight params and knows if the weights buffer needs to be
recomputed or not. So most of the time, updating the WeightsContext is a no-op.
In the future we'll need to add support for interpolating changes to dynamic
weights to avoid abrupt scoring changes.

Included features in this changelist:
* Capture a snapshot of common movement properties (velocity, speed, etc) that are used to drive animation
* Character movement component for stop/pivot location
* Library of anim node functions for Distance Matching
* Template anim node that can advance by distance traveled rather than by time
* Template anim node that's driven by distance to a target rather than by time
* Animation modifier that generates distance curves based on root motion
* Turn in place functionality for keeping the capsule from spinning the pose when it rotates by applying an offset, includes functionality for turn on spot animations to compenstate for the offset

Motion Trajectory Component for Motion Matching:
Motion Trajectory Component notes:
1) Abstract component/interface implemented with prediction and history API.
2) Implemented uniform, frame-rate independent history sampling algorithm for retaining trajectory sample coherence.
3) Implemented concrete Character Movement Trajectory Component for encapsulating ground locomotion prediction algorithm and API.
4) Motion Trajectory blueprint library containing:
5) FlattenTrajectory2D algorithm for isolating and removing Z axis direction contribution from tracjectory.
6) ClampTrajectoryDirection for projecting trajectory samples into a discrete, allowed set of directions (such as cardinal).
Engine changes:
1) Implemented shared TrajectorySample, Range, and Domain structures for common usage among Motion Trajectory, Pose Search, and Blueprint.
2) Expanded Sequence Player blueprint library functionality for Scripted Motion Matching content example.
Pose Search changes:

Also fixes type conversions (first time I have tried to convert to a base class and found that my IsChildOf check was the wrong way around).
Plus some extra accessors added for exec/update contexts.
Found the need for these when doing show & tell prep.

Split 'node context' into an 'evaluation context' and a 'node reference' type and updated regular function signatures when creating node functions. This way we can seperate concerns (and potentially reference anim nodes standalone in the future).
Moved function caller code into function ref file to stop AnimNodeBase bloat.
Fixed functions not being called on root nodes.

Adds 'template' anim BP concept. These anim BPs have no TargetSkeleton and as such cannot have direct references to animations placed inside of their anim graphs
Adds function call support from anim nodes. All anim graph nodes can now call functions when initialized, updated, evaluated or when they first become relevant.
Relevancy is established using a new FAnimSubsystemInstance_NodeRelevancy which tracks nodes in a local map, per UAnimInstance, if nodes require it.
Functions are displayed on the node if bound, and in the details panel.
Added a new override point to FAnimSubsystemInstance to allow for WT init.
Moved FMemberReference customization into a public header so it can be used on anim node functions.
Wrapped functions up into FAnimNodeFunctionRef structure so they can be re-used more effectively. Converted CallFunction node to use them.
Added a couple of simple BP function libraries to demonstrate the use of the new FAnimNodeContext (this is intended to be a generic way of exposing FAnimNode_Base types to script without the node types themselves having to be known to script directly).
Added the ability to set exposed properties as 'always dynamic' so they appear in mutable data rather than being merged into constants. This allows for the anim node data API to be changed to be less strict (and more script friendly). Now values can be set in mutable data (via GET_MUTABLE_ANIM_NODE_DATA_PTR) and attempted sets to constant data can be ignored and reported to client code.
A few minor crash fixes with edge cases (inc when trying to open an asset editor fails because of a missing skeleton/cancellation).
Also fixes an issue where literal linked anim graph/control rig/custom poroperty node inputs didnt get copied
