bmpblk: Remove unused strings and minor updates

Remove translations that are not longer used from xtb files. Apply minor
updates to hu, ro and tr languages, as it seems that latest change to
rec_disk_step2_desc0 triggered translation for some texts that were
translated before.

To collect comprehensive list of changed IDs following command from
strings/locale/README.md was run for all supported language codes.
python3 $CROS/src/platform/bmpblk/update_xtb.py diff <language_code>

All modified IDs where then merged using
python3 $CROS/src/platform/bmpblk/update_xtb.py merge <ID1> <ID2> ...
