ruff: require function annotations

[Javagedes]

Adds the rule ANN which requires function annotations. See https://beta.ruff.rs/docs/rules/#flake8-annotations-ann for more information.

Only adds type annotations to function headers so this will have no effect on the codebase itself.

This is the edk2-pytool-extensions portion of completing this issue: tianocore/edk2-pytool-library#208
