Fix #946: Add standard iterator traits to CharPointer_UTF8 for compatibility with std algorithms

Browse source 
- Added value_type, pointer, reference, iterator_category, and difference_type typedefs
- Enables CharPointer_UTF8 to work with standard library algorithms like std::all_of
- Uses input_iterator_tag as the most appropriate category for UTF-8 character iteration
- Maintains full backward compatibility with existing code
- Tested with both GCC and Clang compilers
