Revert "Remove build-nuget from dml-vs-2022.yml" (#24504)
Reverts microsoft/onnxruntime#24372
The above PR removes the `build-nuget` command-line argument from the
`dml-vs-2022.yml` file. This PR reverts that change and adds the
`build-nuget` back to the file.
The `--build_nuget` option creates the
`csharp\src\Microsoft.ML.OnnxRuntime\bin\RelWithDebInfo` directory
structure and stores binaries in there. There's a subsequent task in the
yaml file that tries to sign DLLs in the
`csharp\src\Microsoft.ML.OnnxRuntime\bin\RelWithDebInfo`, however this
task fails because the directory structure is now never created (due to
removal of `--build_nuget`).
