CI: Introduce CI for libs to Improve code quality and reduce noises

Currently, runtime-rs related code within the libs directory lacks
sufficient CI protection. We frequently observe the following issues:
- Inconsistent Code Formatting: Code that has not been properly
  formatted
is merged.
- Failing Tests: Code with failing unit or integration tests is merged.

To address these issues, we need introduce stricter CI checks for the
libs directory. This may specifically include:
- Code Formatting Checks
- Mandatory Test Runs

Fixes #11512
