Feature/rust bindings: Exterimental bindings (#6467)

* Add files for assimp rust wrapper

* Fix bindgen usage.

* Add missing includes for the rust bindings.

* Apply suggestion from @coderabbitai[bot]

Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>

* Update build.rs

* Fix formatting in Cargo.toml

* Remove generated file
