forkfun a3c2a17d36 MDEV-38967: STR_TO_DATE() cannot be used in indexed virtual columns ...

Update STR_TO_DATE() to accept an optional third argument for the locale.
DATE_FORMAT() and STR_TO_DATE() return NULL when the locale argument is NULL;
issue a warning and fall back to the session @@lc_time_names for invalid locale names.
STR_TO_DATE() can now be used in indexed virtual columns while having all 3 arguments,
but not allowed when 2 as it depends then on the session @@lc_time_names
