vcxproj: handle resource files, too

On Windows, we also compile a "resource" file, which is similar to
source code, but contains metadata (such as the program version).

So far, we did not compile it in `MSVC` mode, only when compiling Git
for Windows with the GNU C Compiler.

In preparation for including it also when compiling with MS Visual C,
let's teach our `vcxproj` generator to handle those sort of files, too.
