This PR adds the first bit of Rust (compiled to wasm) to Glimmer. All tests pass in Chrome and Firefox, investigating Edge and Safari.

It uses https://github.com/glimmerjs/broccoli-rust2wasm … -- which can be used in any Broccoli/EmberCLI project! #itshappening
If the body of every function has to be unsafe, is it really an improvement? I want to see us get there but it still seems immature for real use to me

1. wasm is safe, so there is no such thing an unsafe-rust-in-wasm 2. the first time anyone writes production FFI, it involves "unsafe" code. This is true of virtually all production FFI systems. 3. All tests pass, integration included. It's for real.

Additionally, this is particularly low-level code that tries to avoid using the allocator. But most uses are fine with an allocator, which adds ~4k gzipped to wasm code.
