Introduce QMAKE_CD to enable us to cd from one Windows drive to another

On Windows cd does not change the drive. So when you are on drive C:
and type "cd D:\data" it will change the directory on drive D: but not
affect your current working directory.

To also change your drive you have to provide the parameter /d on
Windows, so "cd /d D:\data" will also change the drive.
