After PR libretro#14821 , the
contents of msg_hash_xx.c files are present in the normal translation
workflow. These files can and should be reduced to stub versions,
since new translations won't take effect otherwise.
These languages had the original English text as help at the time of
commit, so it is safe to assume no translation content is lost.
Some content is preserved until Crowdin translation catches up.
