Cleanup/windows: Remove 32 bit support from make.bat helper script

This change removes 32 bit support from the helper make.bat scripts
as we are dropping official 32 bit support, you can still build for
32 bit by configuring your build yourself using cmake and pointing
the LIBDIR cmake variable to your own 32 bit library folder.
