feat(lint): implement vue/noSetupPropsReactivityLoss Part2

[AsherDe]

Summary

This PR extends the noVueSetupPropsReactivityLoss rule to detect props destructuring in the setup function body, not just in parameters.

PR#7513

Test Plan

Added comprehensive test coverage with 9 new test files covering:

Invalid cases (should report errors):

• Body destructuring in method form: setup(props) { const { count } = props; }
• Body destructuring in arrow functions: setup: (props) => { const { count } = props; }
• Body destructuring in function expressions
• Assignment destructuring: ({ count } = props);
• Array destructuring: const [first] = props;
• Works in defineComponent() and plain object literals
• TypeScript files with type annotations

Valid cases (should not report):

• Safe destructuring with toRefs(props)
• Supports all Vue import sources: vue, @vue/reactivity, @vue/composition-api
• Namespace imports: Vue.toRefs(props)
• Aliased imports: import { toRefs as makeRefs }
• Destructuring in nested functions (callbacks, handlers)
• Multiple exports (only checks export default)

All tests pass:

test result: ok. 1764 passed; 0 failed; 0 ignored

File type support verified:

• ✅ .js files
• ✅ .ts files
• ✅ .vue files (extracts and checks <script> content)
