#rn Add an fbx option to allow compute normals to use weight by area and angle for both staticmesh and skeletalmesh. Add also a staticmesh build options for the feature.

Deprecated direct access to UStaticMesh::SourceModels, SectionInfoMap and OriginalSectionInfoMap.
Added new accessors for getting individual SourceModels, or the entire array.

* Option is disabled by default
* When enabled, the resulting merged mesh will have:
** An additional unused material which is created from the merge of all meshes materials
** An additional set of UV coordinates that can be used to apply the merged material to any section of the mesh
** Added additional static switch params to BaseFlattenMaterials to allow specifying UV channel

Creating a triangle will also create a 'shadow' polygon for backward compatibility, although this is omitted when serializing.
As with polygons, any missing edges are created when creating a new triangle, and operations such as adjacency are available to triangles, just as for polygons.
The native serialization format for MeshDescription is now based around triangles.
Polygons of arbitrary number of edges may still be represented, and when created, will automatically generate the appropriate number of triangles. Polygons of more than three sides automatically generate 'internal edges', which are owned by the polygon, and which will be regenerated if the polygon is retriangulated. Internal edges are otherwise not distinct from other edges, and can be used to determine connected triangles or vertices.
Direct access to public members of mesh element classes (FMeshVertex, etc) is now deprecated. In particular, vertex instances and edges now hold a list of connected triangles, and the ConnectedPolygons member is deprecated and will be removed (as this data can be derived from the ConnectedTriangles list).
Improved the MeshDescription API, providing more operations, and allowing arrays with different allocators to be provided as results containers.
Fixed several MeshEditing operations.
Added MeshDescription unit tests.

* Now extracted from sub levels and brought in the main map to be rendered as instanced static meshes.
* Impostors meshes created during proxy creation.
