Have the windows.resource_compiler() preprocesor write a depfile
When using binutils's windres, we can instruct it to invoke the preprocessor
in such a way that it writes a depfile, so that dependencies on #included
files are automatically tracked.
Not implemented for MSVC tools, so skip testing it in that case.
