371cc9a ProceduralVegetationEditor
First implementation of 2D growth data extraction algrithm

This CL implements the remaining parts if the APIX 2D growth data import algorithm, such that it is possible to generate valid growth data from a 2D image inside of PVE. This CL also moves code which is shared between the 2D and 3D importers from PVImporter_StaticMesh to PVImportHelpers.

Overview:
- Implement remaining 2D growth data import algorithm
- TriangulateCurvesAndSplitEdges
- ComputeVertexScale2D
- FindEndPoints2D
- FindRootPoints2D
- Add support for importing multi-plant assets
- PV::Import::Helper::FillGrowthDataFromBranchHierarchyDescription
- PV::Import::Helper::FillGrowthDataFromFoliageDescription
- PV::Import::Helper::GenerateGrowthDataFromPlantDescription
- Refactor PVImportHelper to allow for sharing of functionality between 2D and 3D importer
- PV::Import::Helper::ComputeBranchHierarchies
- PV::Import::Helper::ComputeLengthFromRoot: Fix issue that caused the wrong branch to be selected as parent branch during import (PVE-167)
- PV::Import::Helper::TraceBranches
- PV::Import::Helper::ExtractBranchHierarchies
- PV::Import::Helper::ConvertMeshBranchHierarchiesToBranchDescription

Main files of interest for this review:
- PVImporter_Texture2D: This file contains the main new algorithms added to complete the 2D growth data importer (TriangulateCurvesAndSplitEdges, ComputeVertexScale2D, FindEndPoints2D, FindRootPoints2D)
- PVImporter_StaticMesh: Shared functionality have been moved out of this file (TDynamicMeshVertexAttributeDefinition, ComputeLengthFromRoot, DrawBranchCurves, RemoveBranchCurveOverlaps, ExtractBranchesFromBranchCurves)
- PVImportHelpers: This file now contains shared import functionality between the 2D and 3D importer. ComputeLengthFromRoot and TraceBranches (new name for DrawBranchCurves) have been re-worked to solve issue PVE-167.

[PVE] Mesh twisting fix
Issue: Calculation of Up Vector for each point was being calculated wrongly, which caused mesh twisting, especially on sharp corners
Fix: Up Vector is now calculated w.r.t the previous Point Up Vector, which works in all cases. Also there was no point of over-calculating AimVector as that was already fine.

8e81a82 UAF
Add UAF Asset Data structure to encapsulate an asset that can be used to generate a UAF graph or system.

The goal of this changelist is to:
* Allow specialization of assets where a UObject* may not be appropriate. For example in control rig, we want to specify a UClass instead of a UObject
* Allow extra data to be passed around with the object pointer, for example a animation sequence could have a specific playback speed. This could only be achieved in the past by the user specifically authoring factory params which exposes a lot of possibilities to the user, some of which are illegal (e.g. they can add any additive trait).
* Provide a layer of abstraction between what the user wants to play (UAFAssetData) and how it will actually be played (trait data). This gives more flexibility in the future to change trait data without breaking user data.
* Allow for specialized UI depending on the asset data type
* Add control rig as a UAF asset type

352111c UAFMirroring
Anim Mixer: Fix mirroring support of skeletal animation sections.

As the first step of supporting mirroring in the mixer, this gets it working in a backwards-compatible way with skeletal animation sections, where the mirror data table is
specified as a property on the Skeletal Animation Section.

We do this by using the existing Mirror Evaluation Task, which is refactored out of the trait file, as well as moving the runtime instance data responsible for mirroring into the task itself rather than leaving it in the trait.

We then append an additional mirroring evaluation task in the case we want to mirror. This strategy allows us to use mirroring on any kind of animation section going forward. That functionality will come in a later changelist.
