…her paper Uwp or fabric Composition prop/targets (#14024) This PR backports #13945 to 0.76. ## Description This PR creates new "entry" prop/target imports for C++ libraries that depend on the `UseFabric` property to conditionally import either the old Uwp props/targets or the new Composition props/targets. ### Type of Change - New feature (non-breaking change which adds functionality) ### Why This helps enable module projects to support both paper and fabric with the same build files. Resolves #13928. ### What Added new imports, updated the `cpp-lib` template and existing sample to load them. ## Screenshots N/A ## Testing N/A ## Changelog Should this change be included in the release notes: yes Update the `cpp-lib` template project to support importing either paper Uwp or fabric Composition prop/targets
