Provided a path for building MeshDescriptions for static meshes at runtime, and supporting API.
Clarified use of attributes for static meshes; now some attributes may be considered optional.
Added FStaticMeshAttributes, used for fetching and registering all the attributes required by a static mesh.
Added Blueprint interface for building meshes.
Deprecated a number of existing APIs:
- FMeshDescription methods which referred explicitly to static mesh specific attributes
- StaticMesh attribute registration has been moved to FStaticMeshAttributes

#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.

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.

- MeshDescription now held as compressed bulk data and unpacked on demand. This is managed by FMeshDescriptionBulkData.
- Made RawMesh accessors in StaticMesh responsible for performing legacy conversion from MeshDescription if necessary.
- Added FBulkDataReader/FBulkDataWriter for serializing bulk data to/from archives.
- Added FUntypedBulkData::UnloadBulkData() for releasing the bulk data allocation without invalidating it (so it can be reloaded when necessary). Editor only.
- Renamed StaticMesh MeshDescription methods (now GetMeshDescription(), CommitMeshDescription() etc).
- Removed unnecessary mesh description attributes from StaticMesh: those which are used only by Editable Mesh, and transient attributes which are automatically generated when needed for building vertex tangent space.
- Slight change to FAttributesSetBase::RegisterAttribute(): if the attribute specified already exists, it will be amended to adopt the type, passed flags and number of indices. If only the number of indices changes, any existing data will be preserved if possible.
- Added TMeshAttributesRef::Copy() to copy an entire attributes array from one name/index to another.
- Changed implementation of TMeshAttributesRef/TMeshAttributesView to provide a const ref/view if the template type parameter is const. Added TMeshAttributesConstRef/TMeshAttributesConstView as an alias for backwards compatibility.
- Added FMeshDescription::IsEmpty() for determining whether a mesh description has any content or not.
- Removed versioning GUID for mesh description: this should be handled by each mesh description client now.

MAJOR FEATURES & CHANGES
============================
Change 4280523 by Patrick.Boutot
Add option in AjaCustomTimeStep to wait until the frame to be ready. Previously, the frame was there but not yet processed so it was possible that it was not ready by the time we wanted to read it. It won't work with interlaced because the 2 fields are processed at the same time. In interlaced, will get a 30fps behaviour when we actually want a 60fps.
Fix bug that didn't set and reset bIsOwned properly when it was first initialized as not owned.
Change 4280526 by Patrick.Boutot
Add accessor to get the leaf media source or output.
Change 4280624 by Patrick.Boutot
Add timecode acessor to media samples
Change 4280626 by Patrick.Boutot
Rework the timing for AJA Media Player. Previously, we took the timing of the frame. That was a bad idea because if 2 incomings video frames were coming a the same time, you would only show one. Making the buffering system useless.
That affects the Custom Time Step since it was waiting for the interrupt signal and in some behavior we would like the frame to be ready to be used by UE. Same the timecode in the MediaSample because we may not used it to stamps the frame.

Allow UHT to parse FText default parameter values
INVTEXT, NSLOCTEXT, LOCTABLE, and FText::GetEmpty() are supported. LOCTEXT isn't as it relies on an external macro that is known to C++ but not to UHT (NSLOCTEXT can easily be used instead).

- Removed TMeshAttributeArraySet::AddArray because the functionality was already available as part of SetNumIndices.
- Renamed TMeshAttributeArraySet::InsertArray, RemoveArray to InsertIndex, RemoveIndex for naming convention consistency (these methods deal with attribute indices, not with arrays). Added support for them in other attribute classes, and made them virtual so they can be called as part of an AttributesView.
- Removed redundant code in FUSDStaticMeshImportState::AddPolygons, when determining the number of UVs in the mesh description.
