ComWrappers support

[kant2002]

I manage to work WinForms in NativeAOT context using global ComWrappers, and made attempt to do the same, but hit a roadblock with Marshal.ReleaseComObject. See dotnet/runtime#54317 for more information.

Having ComWrappers for this repo make WPF more a tiny bit more friendly for IL Trimming.
I'm willing to follow advised direction, and implement some ComWrappers for this repo, if this is what team are willing to take as contribution.

I’m also happy to take on this task. After we replace all the uses of ComImportAttribute with ComWrappers, someone could then attempt to rewrite the C++/CLI assemblies in a combination of unmanaged C++ and C#. If that too could be accomplished, then I could run WPF apps through NativeAOT and have everything “just work.” This would be extremely, extremely cool. I don’t know how breaking a change removing C++/CLI would be, however.

it would be great if wpf could support ComWrappers.

Speaking of C++/CLI, there is ongoing work on porting DirectWriteForwarder to C#: #5305.
