Zihan Chen (MSFT) 9bb71650c9 Add @react-native/codegen-typescript-test to verify .d.ts files in @react-native/codegen (1) (#36562) ...

Summary:
- Add a typescript project to test `CodegenSchema.d.ts`. More tests for other .d.ts files will be added in future pull requests.
- The build script scans all snapshots from `react-native/codegen`'s typescript frontend and generates .ts files for each snapshot, but they are .gitignore-ed.
- `npm run build` will build these .ts files against `CodegenSchema.d.ts` after generating them.
- A failed jest case is included to ensure CI catch it, it will be removed before merged.
