Initial conflict resolution of SD_REPRINT_LAST_SELECTED_FILE (#8104)

* Initial conflict resolution

All previous items resolved:
- Use of ELAPSED() on timer code
- Switch to use of defer_return_to_status=true as much as possible
- Update & Clean Up of Max7219 routines

* Resolve non-SD case in ultralcd.cpp

Marlin/cardreader.cpp
