Documentation: ext4: Document casefold and encrypt flags
Based on ext4(5) and fs/ext4/ext4.h.
For INCOMPAT_ENCRYPT, it's possible to create a new filesystem with that
flag without creating any encrypted inodes. ext4(5) says it adds
"support" but doesn't say whether anything's actually present like
COMPAT_RESIZE_INODE does.
