This removes the need to hand-write rust_wrapper.c, because bindgen can generate it for us. bindgen 0.65 or later is needed. Earlier versions of this were buggy. I've also removed the claim that bssl-sys is somehow a solution for version skew. That was the original thinking from Android, but it hasn't worked out. The version skew solution is simply "use bindgen, don't handwrite bindings". Android are quite behind their originaly July timeline for adding the build half of this mechanism, but as this is now in the way of other work, we're going to proceed with using this now. There is now a unsupported_inline_wrappers cfg that Android can set to use the old mechanism. Update-Note: Rust support now requires your build correctly handle --wrap-static-fns. On Android, you will need to enable the unsupported_inline_wrappers cfg option until b/290347127 is fixed. Chromium doesn't actually use any of the inline functions yet, so we can handle --wrap-static-fns asynchronously, but I have a CL ready to enable that.
