cpp-builder: Keep all data files in the project directory

- Output the executable file to the project directory.
- Save layout data in `data.dat` in the project directory.
- Keep nwind.db in the project directory: resolves the problem with
  failed database connection in Report Designer.
- Upgrade the project to RAD Studio 13.
- Remove unnecessary include paths from the project settings.
