What problem does this PR solve?
Issue Number: close #58870
Problem Summary:
When it is text-prepare, SQL will be parsed twice. The first time, it is already transformed to utf8 due to
charset_client. Thus when it comes to executor, only the other two parameters need to set.But if it is coming from prepare protocol, SQL have not been parsed before. We also need to set
charset_clientto transform it to utf8.Check List
