CMake: Re-implement configure/qmake's command line handling in CMake

We extend configurejson2cmake to read the "commandline"
information from configure.json. This data is then translated to CMake function
calls and written it into commandline.cmake files.

We extend QtProcessConfigureArgs.cmake to pick up those commandline.cmake
files to feed our command line handling code, which is a
re-implementation of the command line handling in qt_configure.prf.

The command line handler sets INPUT_xxx variables, similar to
configure/qmake's config.input.xxx variables. The INPUT_xxx values are
translated
- to -DFEATURE_xxx=ON/OFF arguments if the input represents a feature,
- to corresponding CMake variables if such a variable is known,
- or to -DINPUT_xxx=yyy CMake arguments.

Configure arguments that have an entry in
cmake/configure-cmake-mapping.md are actually implemented. Other
arguments are likely to need more work.
