Install Rust Toolchain

This GitHub Action installs a Rust toolchain using rustup. It further integrates into the ecosystem. Caching for Rust tools and build artifacts is enabled. Environment variables are set to optimize the cache hits. Problem Matchers are provided for build messages (cargo, clippy) and formatting (rustfmt).

The action is heavily inspired by dtolnay's https://github.com/dtolnay/rust-toolchain and extends it with further features.
