Set Casefold and PrjQuotas in Factory Reset
This sets up devices to have casefolding and project quotas if they have
enabled the relevant product properties. For ext4, we must set wide
inodes at makefs time, but other things are enabled by fs_mgr with
tune2fs at boot time.
Bug: 138321217
Bug: 138322712
Test: Enable on a device.
Reformat from recovery. Check that /data has the expected values
using tune2fs/f2fs.fsck
