Bug 1792615 - Run "cargo +nightly fmt" for style components in servo. r=emilio

The directories changed:
* servo/components/selectors/
* servo/components/style/
* servo/components/style_derive/
* servo/ports/geckolib/

Per review request, disable rustfmt in `components_to_transform_3d_matrix()` to
preserve the format for a call to `Transform3D::new`.
