Bugfixes:
* AST: Do not output value of Yul literal if it is not a valid UTF-8 string.
* SMTChecker: Fix internal error on struct constructor with fixed bytes member initialized with string literal.
* Source Locations: Properly set source location of scoped blocks.
* Standard JSON: Properly allow the ``inliner`` setting under ``settings.optimizer.details``.
* Type Checker: Fix internal compiler error related to having mapping types in constructor parameter for abstract contracts.
