HLOD useLODAImposter seems to not copy over all UV channels
Mesh merging code was assuming the UV2 & UV3 channels were free to use to store position & scale of imposter instances.
This behavior seems to have been hacked in the engine for an internal project & is not needed anymore since it's now possible to use instanced static meshes with LODActors
Still kept old behavior around (CVar) in case someone would really need it

Added new accessors for getting individual SourceModels, or the entire array.

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

There was a second crash after this one where the code did not call RegisterMeshAttribute on a newly created FMeshDescription.

- 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.
