Objective-C/Objective-C++ Support

[PathogenDavid]

Objective-C and Objective-C++ support are both almost non-priorities for Biohazrd due to their limited use outside of MacOS.

However, it may not entirely be unreasonable seeing as Clang does support these languages. It may also be simplified/enabled by dotnet/runtime#44659

This issue is unlikely to see progress without it being sponsored specifically. This issue is mostly for me to keep track of relevant references for if this development on this ever happens.
