In some edge configurations two 'terminator' vertices (at the end of open bevel edge paths) are directly connected by a non-bevel edge that we will "open", and this creates a quad-shaped hole instead of a triangle-shaped hole (which was already handled). Detecting this case will arise is simpler before we change the topology, so it is done in BuildVertexSets(), stored in FBevelVertex::ConnectedBevelVertex, and used during mesh generation to call new AppendTerminatorVertexPairQuad function.
In BuildTerminatorVertex(), the search for a terminator split-edge may fail if the filtered triangle list ends up non-contiguous, preventing the vertex from being beveled (ie it is "stuck"). Code was added to both handle that case, and also try to force the list to stay contiguous.

ModelingTools: add support for writing to selected group layer, as well as new group layer, in ConvertToPolygonsTool (GrpGen in UI). Also add support for setting groups from existing layer, which (combined) allows copying groups between layers, duplicating existing layer, and so on.

GeometrySelectionUtil: add FindByTopologyID function, to search a Selection for selected element with matching TopologyID but ignoring GeometryID. Update FGeometryScriptMeshSelection::CombineSelectionInPlace() to use this, as it was not properly combining Polygroup selections.

GeometryScriptSelectionTypes.h:
New type FGeometryScriptMeshSelection stores Vertex, Triangle, and Polygroup selections. Currently internally represented as a TSharedPtr<FGeometrySelection>, however this is not exposed to BP at all. FGeometryScriptMeshSelection is an opaque object w/ no exposed properties, and it's contents cannot be serialized, ie it is only usable as temporary data during active GeometryScript computations.
MeshSelectionFunctions.h: library of functions for creating/manipulating mesh selections
CreateSelectAllMeshSelection - create a Mesh Selection for all elements of Mesh
ConvertMeshSelection - convert a Mesh Selection to a different type
CombineMeshSelections - combine two Mesh Selections using set operations (union, difference, intersection)
ConvertIndexArrayToMeshSelection / ConvertIndexSetToMeshSelection - convert TArray<int> / TSet<int> to a Mesh Selection
ConvertIndexSetToMeshSelection - convert a Mesh Selection to TArray<int>
ConvertIndexListToMeshSelection / ConvertMeshSelectionToIndexList - convert between an Index List and a Mesh Selection
SelectMeshElementsInBox, SelectMeshElementsInSphere, SelectMeshElementsWithPlane - create a Mesh Selection of all elements "inside" a geometric element
SelectMeshElementsByNormalAngle - create a Mesh Selection of all elements based on normal vector direction
SelectMeshElementsInsideMesh - create a Mesh Selection of all elements inside another mesh (with optional extra shell thickness)
ExpandMeshSelectionToConnected - expand a Mesh Selection to Connected regions (various connectivity criteria)
GetMeshSelectionInfo - get the type and size of a Mesh Selection
DebugPrintMeshSelection - print a Mesh Selection to the output log
MeshSelectionQueryFunctions.h: library of functions for doing mesh queries based on a selection
GetMeshSelectionBoundingBox - get the bounding box of a Mesh Selection
GetMeshSelectionBoundaryLoops - get the boundary loops (indices and 3D polylines) of a Mesh Selection

Also removed artefacts that became visible after the ones fixible with a depth test were resolved. These were related to linearly interpolating data on the photosets, this was fixed since the baking framework is where texture filtering should take place
