Pull Request Overview

Adds helper shortcuts and corresponding CodeQL implementations to simplify accessing function parameters and call arguments in the Rust AST.

• Introduces synthetic params and args fields in the schema for Callable and CallExprBase, respectively.
• Implements getParam and getArg overrides in the CodeQL internal modules.
• Updates imports, linguist settings, and generated file lists to wire in new extractor tests.

• [nitpick] Add a QLdoc comment above getParam describing its behavior (retrieves the parameter at the given index) and its return type.

override Param getParam(int index) { result = this.getParamList().getParam(index) }

rust/ql/lib/codeql/rust/elements/internal/CallExprBaseImpl.qll:32

• [nitpick] Add a QLdoc comment above getArg explaining that it returns the call argument at the specified index.

override Expr getArg(int index) { result = this.getArgList().getArg(index) }
