Avoid listing the same input more than once in custom commands generated in `.vcxproj` and `.csproj` files. In the case of a `.vcxproj` file additionally avoid listing the source to which the command is attached since it is already implicitly a dependency. This is a nice cleanup and also works around a VS 2019 16.1 regression in MSBuild dependency checking. Starting with that version, MSBuild now re-builds custom commands when the list of dependencies has changed. However, its check is confused by duplicate dependencies. De-duplicating them avoids this problem. Co-Author: Brad King <brad.king@kitware.com> Fixes: #19303
