### Description
<!-- Describe your changes. -->
- Update docfx usage.
- The docfx cli is now a dotnet tool.
- Split some commands up so it's easier to debug failures
- Update to .net8.
- Exclude mobile targets from build as the workloads aren't available
and it doesn't change the generated documentation.
- The mobile specific APIs (e.g. enable CoreML EP) still exist in this
case as we check in the implementation if it's valid to use them or not,
so the workloads are not required to generate complete API
documentation.
