winverbs: use export/import function appropriately

Winverbs defines WvGetObject that users must invoke to obtain the winverb provider interface.  WvGetObject is defined in the header files as dllexport, but callers require dllimport.  The winverbs sources file already defines EXPORT_WV_SYMBOLS that is intended to distinguish if we are really trying to export or import WvGetObject. Update winverbs.h to support dllimport for clients including
winverbs directly.
