Refactor GxDynamicCall: fix props, improve assembly loading

Added missing using directives and a public AssemblyName constant. Fixed property setters for Properties and ExtendedProperties. Enhanced VerifyDefaultProperties to use the AssemblyName constant, improved cross-platform assembly loading logic, and added better exception handling for load failures. These changes improve correctness, maintainability, and compatibility.
