fs_mgr: add overlayfs handling for squashfs system filesystems /cache/overlay directory in support of overlayfs mounts on userdebug and eng devices. Overlayfs in turn can be capable of supporting adb remount for read-only or restricted-storage filesystems like squashfs or right-sized (zero free space) system partitions respectively. Test: compile Bug: 109821005 Bug: 110985612 Change-Id: I3ece03886db7cc97f864497cf93ec6c6c39bccd1

fs_mgr: add /mnt/scratch to possible overlayfs support directories A default set of options are available, but can override in a fstab overlay entry with upperdir=, lowerdir= to the same mount point, workdir=. The default is a valid /mnt/scratch/overlay/ or /cache/overlay/ directory, with .../<mount_point>/upper and .../<mount_point>/work, associated with each system partition <mount_point>.
