[tools] Add generate_localization.sh consume command

`./tools/unix/generate_localizations.sh consume` updates `strings.txt`
from generated Android or Apple translations. This feature is only
needed as a backup plan for case if Weblate migration complete fails.
In the worst case scenario, this new command can update `strings.txt`
with translations added outside (by Weblate or other tools).
The full clean round-trip is not intended, but the diff is minimal.
