Fix memory leak with lower, upper and initcap with ICU-provided collations
The leak happens in str_tolower, str_toupper and str_initcap, which are
used in several places including their equivalent SQL-level functions,
and can only be triggered when using an ICU-provided collation when
converting the input string.
b615920 fixed a similar leak. Backpatch down 10 where ICU collations
have been introduced.
