-Added a Blend function overload that handles barycentric interpolation of 3 skin weights.
-Refactored SetBoneWeightsFromBary (in DynamicVertexSkinWeightsAttribute.h) and ConstructVertexSkinWeightsAttribute (in SelectiveTessellate.cpp) functions to use the newly added Blend function for barycentric interpolation.
-Since the default Blend behavior has changed, make sure that unit tests in BoneWeightTests.cpp are refactored. Added more tests for cases when bBlendZeroInfluence is set to true and when using Blend for barycentric interpolation.

The main change is that FSoftSkinVertex, used by FSkeletalMeshLODModel, in now stores weights as 16-bit after conversion from the import data. This increases the size of each FSoftSkinVertex from 144 bytes to 160 bytes (about 10% increase). By default render meshes still use 8-bit skin weights, with weights downshifted from the 16-bit modeling data, so no change in GPU memory consumption there. However, the vertex buffer will automatically return a 16-bit skin weights when requested from the GPU side (e.g. for CPU skinning and viewing tangents).
This change in the model data and vertex buffer CPU-side query, resulted in many changes throughout the codebase and will have an effect on licensees who are actively reading from and writing to these two storage locations.
The GPU skin cache shader has had one more permutation added when not using unlimited skin weights. The vertex factory is not affected.

- Removed implicit casts between FEulerTransform and FTransform
- moved interrogator and tokens inside of sequencer to use FEulerTransform
- added the notion of a preferred rotator for Controls. transform takes precedence for runtime solves, but UI / sequencer relies on the preferred rotator

Register new SkinWeights mesh descriptor attribute that combines weights and influence in a single attribute, that proxies TBoneWeight to allow setting bone weights in one shot with normalization, culling, etc.
Deprecated and removed InfluenceBones and InfluenceWeights and updated the calling code to use the new attribute.
