VS: Fix C++ modules in source files with the same name
When multiple source files in a single target have the same name, we
already set `ObjectFileName` explicitly to avoid a `.obj` collision. For
C++ module sources, set `Module{Output,Dependencies}File` to avoid
`.ifc` and `.module.json` collisions.
Fixes: #25038
