Create directories for snapshots of DE_n and CE_n apex data.

Browse source 
This creates apexrollback directories under /data/misc_[de|ce]/<user>
which will hold snapshots of DE_n and CE_n apex data directories
(i.e. it will hold backups of data from /data/misc_[de|ce]/<user>/apexdata
for particular apexes).

See go/apex-data-directories for details.

Bug: 141148175
