script_binding: Add type check on servo script bindings (#38161)

Introduce type checking with Pyrefly in `components/script_bindings`

This commit adds Pyrefly-based type checking to the
`components/script_bindings` directory. The primary goal is to catch
type inconsistencies early and reduce the likelihood of unexpected
runtime errors.

This change affects the `webidl` component, as these script bindings are
responsible for connecting WebIDL specifications to the Rust codebase.

Testing: `./mach test-wpt webidl`
Fixes: *Link to an issue this pull requests fixes or remove this line if
