`unnecessary_semicolon`: do not lint if it may cause borrow errors
Before edition 2024, some temporaries used in scrutinees in a `match` used as the last expression of a block may outlive some referenced local variables. Prevent those cases from happening by checking that alive temporaries with significant drop do have a static lifetime. The check is performed only for edition 2021 and earlier, and for the last statement if it would become the last expression of the block.
