Subject: [PATCH] Remove references to stale winmd files to fix incremental
 builds (#1404)

The original attempt at a fix for this was too aggressive:
https://github.com/microsoft/cppwinrt/pull/1381/files

This fix is targeted specifically at removing references to stale winmd files that have yet to be copied from referenced projects (e.g., from a runtime component to an app).
