Alexandru Croitor 8ffb6ce64c CMake: Add a config.redo script similar to qt5's config.status 
The config.redo script can be executed to reconfigure a pre-existing
qt build dir with the configure options that were last passed to the
build.

It just calls the original configure script with the -redo option.

It's nicer than calling configure + -redo manually because you don't
need to write out the full source path for configure.

In qt 5 times this script was called config.status.

On windows the script is called config.redo.bat.

Rename the config.redo file that QtWriteArgsFile.cmake writes to
to config.redo.last, so it doesn't conflict with the name of new
config.redo script.

Amends 5c40cb0f1a

Pick-to: 6.5 6.6
