qt, cpp: Add cmake config files for w32

* lang/cpp/src/GpgmeppConfig-w32.cmake.in.in
lang/qt/src/QGpgmeConfig-w32.cmake.in.in: New.
* lang/cpp/src/GpgmeppConfig.cmake.in.in,
lang/qt/src/QGpgmeConfig.cmake.in.in: Remove libsuffix handling.
* lang/cpp/src/Makefile.am,
lang/qt/src/Makefile.am: Create / install w32 config files.
* configure.ac: Configure them.

--
To work with DLL's cmake needs to know about the implib and
the final DLL. So the config files look different enough
that it's better to use alternative files.
