CMake: Introduce qt-configure-module

Add a convenience script to configure a Qt module separately.
This script reads and interprets the qt_cmdline.cmake files of the
Qt module to be configured and eventually calls qt-cmake-private.

Example usage:
<install-prefix>/bin/qt-configure-module <source-root>/qtdeclarative
  -qml-network -- --trace-expand --trace-redirect=cmake.trace
