In PHP8.1, a number of functions who were accepting null arguments will only accept
string ones.
(see https://wiki.php.net/rfc/deprecate_null_to_scalar_internal_arg)
In the polyfill, mb_* functions are already declared with a strict type checking of "string".
Therefore, it is necessary to get rid of the use of non string arguments when calling mb_* functions,
so that it won't break when either using the polyfill,or future php8 versions.
In every call where the argument may not be a string, this commit enforces the string type of the argument (with transtyping)
--- For reviewers
* I generally don't like transtyping, but found it was the more "secure" way (on a non-BC point of view) here.
Specially in Console/Helper/Table.php, where $cell can be an object (there are 2 "$cell instanceof ... tests)
However, where the argument can already be either null or string (and not anything else), there may a beter approach ?
* It's the first time I send a PR on symfony, so don't hesitate pointing me to thinks I've forgotten to done.
