f310c00 Water
[Water]

Removed assert in water quad tree when transition materials are missing. The assert can trigger in normal user interaction flows if a material fails to compile while assigning to a lake/ocean transition material.

Instead, we now log a warning and fall back to the primary water material which are guaranteed to be valid water materials or the default surface material.

[PVE] Exposing grower settings outside its node
- Exposed pins for growth settings on its node.
- Created grower settings and their data and type-related classes.
- Eventually, these classes will be removed when PCG implements struct overridable pins.
- There are some issues, like they are not derived from PVData because they are not dependent upon ManagedArrayCollection and don't need any visualization. We will tackle these issues separately if needed.

Split 2D importer output into one pin per plant

This CL changes the behavior of the 2D Importer such that it outputs one collection per plant, instead of combining them all into one big collection.

Since this CL required larger changes in PVImportHelper, I took the opportunity to perform some minor cleanup of this file (re-name namespace, move relevant contents of PVPlantDescription to PVImportHelper).

PVImportHelper changes:
- Split "ComputeBranchHierarchies" into "ComputeDynamicMeshBranchHierarchies" & "ConvertDynamicMeshBranchHierarchiesToBranchDescription" to allow the importers to map the output to correct part of the mesh
- Rename namespace "Import::Helper" to "ImportHelper"
- Remove FPVFoliageDescription as it will not be used for 5.8
- Move FPVBranchHierarchyDescription into PVImportHelper (also remove USTRUCT and PROPERTIES from FPVBranchHierarchyDescription)
- Change name and signature of GenerateGrowthDataFromPlantDescription to allow passing of an array view (to avoid copying the input branch descriptions at the call-site)

Importer_Texture2D changes:
- Remove debug states which are no longer needed due to better visualization
- Output multiple collections
- VisualizationCollection: (Holds the visualization which is shown to the user to help with tweaking parameters)
- DebugCollection: (used for development, should probably be removed before 5.8 release)
- CombinedOutputCollection: Multi-plant collection which contains all plants which were successfully extracted from the image
- PlantCollections: An array of collections holding one plant each, maps 1-1 to the PlantSettings property in the FPVImportTexture2DParams
