Add ufbx for FBX importing

Browse Source 
This update introduces a new import method for FBX files using ufbx. If the fbx2gltf import fails, it will use the most recently cached scene from the ufbx import. The process is sped up by introducing threads to load the ufbx portion.

Key changes include:

- Support for importing geometry helper nodes in FBX files.
- Addition of cameras and lights with updated names.
- Removal of the fbx importer manager.
- Introduction of ModelDocument3D and updates to its methods.
- Changes to FBX import options and visibility.
- Updating the documentation and handling some errors.
- Store the original non-unique node, mesh and animation names in FBX and glTF.

The FBXDocument handles FBX documents. It provides methods to append data from buffers or files, generate scenes, and register/unregister document extensions.
When exporting FBX from Blender, use the "FBX Units Scale" option. The "FBX Units Scale" option sets the correct scale factor and avoids manual adjustments when re-importing into Blender, such as through glTF export.

Importer for the [code].fbx[/code] scene file format.
</brief_description>
<description>
Imports Autodesk FBX 3D scenes by way of converting them to glTF 2.0 using the FBX2glTF command line tool.
The location of the FBX2glTF binary is set via the [code]filesystem/import/fbx/fbx2gltf_path[/code] editor setting.
This importer is only used if [member ProjectSettings.filesystem/import/fbx/enabled] is enabled, otherwise [code].fbx[/code] files present in the project folder are not imported.

Gets additional arbitrary data in this [GLTFAnimation] instance. This can be used to keep per-node state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
The argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the GLTF file), and the return value can be anything you set. If nothing was set, the return value is null.
