Vilas Bhat 23425fbc54 16KB: Move copy_efs_file_to_data script to gs-common 
There are 4 partitions that are flashed at the factory and use F2FS
fs with 4KB block size:

- /dev/block/by-name/efs
- /dev/block/by-name/efs_backup
- /dev/block/by-name/modem_userdata
- /dev/block/by-name/persist

These partitions can NOT be mounted by 16KB kernels because F2FS
expects BLOCK_SIZE == PAGE_SIZE.

In order for the files in these partitions to be accessible to 16KB
kernels, the dump.f2fs tool is used.

This change will perform these steps at boot time ONLY for 16KB mode.
For every partition (efs/efs_backup/modem_userdata/persist):

1. Use dump.f2fs to copy the content of the partition
   to /data/vendor/copied/<partition name>.img.
2. If the copy was succesfull, rename /data/vendor/copied/<partition
   name>.img to /data/vendor/copied/<partition name>
3. fsync the content of the directory /data/vendor/copied/<partition
   name>.

After the content of the partitions is in /data/vendor/copied,
bind-mount the partitions to the directory /mnt/vendor. See
conf/fstab.efs.from_data.

Note: This change ONLY applies to 16KB kernels. This change does not
modify the original partitions.

Test: Boot test and Enable16kbTest for Pixel 8 & Pixel 9 targets
      Fingerprint and Phone Calls work in 16KB mode
