Subject: UseSWIG: Change the library suffix to 'dylib' for C# on macOS

When testing on macOS, the command `swig_add_library("mytarget")`
creates a library `libmytarget.so` instead of `libmytarget.dylib`.
Subsequently, the library is not found by `dotnet` and the
swig-generated `DllImport` statements.

Fixes: #23967
