Bug#32510 LIKE search fails with indexed 'eucjpms' and 'ujis' char column

Problem: some collation handlers called incorrect version of my_like_range_xxx(), which led to wrong min_str and max_str, so like range optimizer threw away good records. Fix: changing the wrong handlers to call proper version of my_like_range_xxx().
