- Added `Standard_MACRO_DEPRECATED` macro to mark preprocessor macros as deprecated with compiler-specific warning generation
- Simplified deprecated macros (`Standard_OVERRIDE`, `Standard_DELETE`, `Standard_FALLTHROUGH`, `Standard_NODISCARD`, `Standard_THREADLOCAL`, `Standard_ATOMIC`, `Standard_Noexcept`) to expand directly to their C++11/C++17 equivalents while emitting deprecation warnings
- Removed complex conditional compilation logic that checked for compiler/standard support
