VS: Fix VS 2015 .vcxproj file value for GenerateDebugInformation (#15894)

Starting with VS 2015 the GenerateDebugInformation build property is an
enumeration (`No`, `Debug`, `DebugFastLink`) instead of a boolean value
(`false`, `true`).  For now we simply change to `No` and `Debug` fix
current behavior.  Support for `/debug:fastlink` can be added later.
