FatFS and general file operations fixes
* Make FatFS thread safe via malloc and remove alloca. * Fix memory leak from emmc gpt parsing * Always unmount SD card in menu and when launching * Use folders for Backup/Dump/Restore operations * Add error report for some important f_opens * Don't let partial dumping if backup chosen is not GPP or USER.
