Add RustCargoSteps workflow (#468)

Adds a Rust workflow that makes sure the code is well formatted, doesn't
have Clippy errors, and that tests that are passing and validate the
documentation.

This workflow is synced with these repositories:
- microsoft/mu_basecore
- microsoft/mu_plus
- microsoft/mu_rust_helpers
- microsoft/mu_rust_hid
- microsoft/mu_rust_pi
- microsoft/mu_tiano_platforms

This has been tested on a dummy repository.
