Add reference to the new header file in the MSVS project files

Since 572db9c0a1, files.bkl instructs to create in the pre-MSVS2010 wx_*_base.vcproj files references to the winver.h header file so we need to regenerate these project files in the repository.
MSVS2010+ project files also have to be updated to reflect this change.
