Tweak M600 display resume

- Add startFileprint(); call to M108 display routine to fix progress and ensure "printing done" gets shown
- Add SD printing check in marlin_main.cpp M600 routine to skip TFTstate if not necessary (e.g. USB printing)
- Move routine to the top again to ensure immediate execution
