Previously, we rely on mount points to copy files out of
efs partitions. Switch over to dump.f2fs to read directly
from block device without mounting. This allows us to copy
files out of efs partition in both 4K and 16K mode.
Test: Boot dev option enabled ext4 device
Bug: 340965747
Change-Id: I9d3f3d5200adc31f13298488b5be068b0fe7c7f4
Since /persisit was previously mounted during eraly-init stage,
this CL delays the /persist mount to post-fs-data stage.
Actions which depends on the /persist partition are also moved.

During boot, this CL adds the following sequence of actions:
1. mount original efs partitions(most likely f2fs) on /mnt/vendor/efs
2. copy files in /mnt/vendor/efs to /data/vendor/copied/efs.img
3. fsync all the files in /data/vendor/copied/efs.img
4. rename /data/vendor/copied/efs.img to /data/vendor/copied/efs
5. bind-mount /data/vendor/copied/efs to /mnt/vendor/efs
6. repeat 1-5 for efs_backup and modem_userdata
The original EFS partitions are mounted and only used for file
copying, no destructive action done on original efs partitions.
Test: reformat /data as ext4, boot the device
