build: manage toolchain via `rust-toolchain.toml` #168

This ensures that:

All targets and components required are always available both in local dev environments and CI
There's only a single toolchain used for everything
Rustup is not a dependency for development
There's just a single place where the Rust toolchain version and component sets are maintained

I prefer to stick to using a stable toolchain whenever possible and only using nightly as a last resort, so I would prefer to keep the current design.

We are aiming to wind this repo down and have everything living upstream (in the wasmtime repo) this month, so I don't think we should change how we manage this now.
