Problem Description

While updating the new arch templates for apps and libs to use the new arch NuGets packages (see PR #13338), we sometimes hit the following error:

.nuget\packages\microsoft.windows.cppwinrt\2.0.230706.1\build\native\Microsoft.Windows.CppWinRT.targets(228,13): error MSB4006: There is a circular dependency in the target dependency graph involving target "CppWinRTComputeGetResolvedWinMD".

This appears to be a known issue in CppWinRT when using a Windows Packaging project that relies on any projects that use CppWinRT: microsoft/cppwinrt#950. If projects are built fast enough and in parallel, you end up in a situation where CppWinRT gets confused when generating headers.

My guess is this is only reproing now with the switch to NuGets for the new architecture templates, which drastically speeds up their builds. This only affects the first build, if you build a 2nd time it usually works because the headers for one project will already be done.

Otherwise, the only solid workaround is to disable multi-proc builds by passing --singleproc to run-windows.

Steps To Reproduce

1. Create a new library project with create-react-native-library WITH an example app
2. Add RNW and then add the windows project with init-windows --template cpp-lib
3. NAvigate to the example app folder and try to build with run-windows.

Expected Results

The example app builds successfully the first time.
