Fixes dotnet#15343. CoreCLR does not like running into methods declared as internal calls: [MethodImplAttribute (MethodImplOptions.InternalCall)] and will fail with an error, even if the method is never executed, just encountered by the JIT: ECall methods must be packaged into a system module In the early days of .NET support we solved this by adding an indirection for CoreCLR, where the internal call was hidden inside a managed call that would never be executed at runtime. This seems to work fine in most cases, except when the debugger attached, when I'm guessing the JIT is more aggressive, and looks further ahead (and fails). On the other hand, in the early days of .NET support on macOS the managed code had to work for both Mono and CoreCLR without modification (since the same implementation assembly would be picked by the build independent on the actual runtime). This is no longer the case, since we only support CoreCLR on macOS now, which allows us to put any Mono-specific managed code (such as the internal call) in !macOS conditions. Fixes dotnet#15343.
