Include ijwhost in DesignerRuntimeImplementationProjectOutputGroupOutput

[elinor-fung]

ijwhost is required for C++/CLI assemblies. If a project that has a designer (like WinForms) references a C++/CLI assembly, it needs to be told about ijwhost.

It looks like there is no automated testing support for C++/CLI projects right now due to #11008. I just manually ran msbuild /t:DesignerRuntimeImplementationProjectOutputGroup on a C++/CLI project and checked that ijwhost was in the target outputs.

Would it be possible to validate the end-to-end scenario where this will fix the designer loading?

I asked @Shyam-Gupta over e-mail if he could validate.

Looks good. Note that the main branch is for the .NET 8 SDK, you should probably retarget this to release/7.0.2xx if you want this to go in the next feature release of the SDK.

Thanks - retargeted. I don't know much about the release/branching in sdk - is release/7.0.2xx open or is there some sort of approval process? Does it flow back to main or would I need to port it?

release/7.0.2xx is open and changes will automatically flow into main (eventually).
