Remove support for Win9x from wxMSW.

Most importantly, this allows us to remove all MSLU-related stuff.

Some functions which were previously loaded dynamically can now be just used
directly, too.

-// Set wxUSE_UNICODE_MSLU to 1 if you're compiling wxWidgets in Unicode mode
-// and want to run your programs under Windows 9x and not only NT/2000/XP.
-// This setting enables use of unicows.dll from MSLU (MS Layer for Unicode, see
-// http://www.microsoft.com/globaldev/handson/dev/mslu_announce.mspx). Note
-// that you will have to modify the makefiles to include unicows.lib import
-// library as the first library (see installation instructions in install.txt
-// to learn how to do it when building the library or samples).
-//
-// If your compiler doesn't have unicows.lib, you can get a version of it at
-// http://libunicows.sourceforge.net
-//
-// Default is 0

-// Recommended setting: 0 (1 if you want to deploy Unicode apps on 9x systems)

 // Set this to 1 if you want to use wxWidgets and MFC in the same program. This
