.pytool/CISettings.py: Set rust-ci scope and use in tree BaseTools

The Rust BaseTool changes are not in the edk2-basetools PIP module,
so this change updates CISettings.py to use the in tree tools by
default.

The `rust-ci` scope is added as an active scope so Rust related
plugins like `RustHostUnitTestPlugin` will run.
