Non virtual calls to instance methods non-virtual dispatch on instance interface methods (dotnet/coreclr#27756)

* est for non_virtual_calls_to_instance_methods
* Fix handling of callvirt to instance methods on interface types that are not virtual
- Use call type to indicate if its non-virtual or not, instead of opcode
* Use ilproj to protect against future C# compiler changes
- This test needs to test the use of specific opcodes, and so an IL proj is required
