Use bindgen to generate API code #6

[x] Somewhere in mmtk-ruby we compute struct offsets using the memoffset crate. That carries a dependency on the nightly version of Rust. Remove it.
[ ] Use rust-bindgen to generate Rust counterparts of Ruby structs in C
[x] Use cbindgen to generate the mmtk.h used in the ruby repo.

We have been using cbindgen to generate the mmtk.h header since this commit: https://github.com/mmtk/mmtk-ruby/commit/86ff3d29857e8a8f24160207c3df353c8d2cb9a6

We will need to look directly into Ruby objects when we start to optimise object scanning. Then we'll use rust-bindgen to generate the binding in the other direction.
