CodeQL supports Rust [GA]

### Value Prop

Rust is becoming a more popular languages and more enterprises are adopting it as an alternative to C/C++. Rust support for CodeQL allows organizations to analyse their proprietary Rust codebases for potential security vulnerabilities.

### Expected Outcome

Users using Rust to build their applications will start seeing files written in Rust included in the list of files scanned by CodeQL. This means that they will potentially see new CodeQL relevant to Rust. This will help find and fix issues from additional code bases and improve the overall security posture of the applications scanned with CodeQL.

Start with the issue's expected outcome: Rust files should be included in CodeQL scans and produce Rust-relevant results. The payload names no implementation files, tests, or entry points, so determine the relevant CodeQL components and define completion around Rust code being scanned and findings being reported.
