Launch Solidity Compiler v0.8.28 with Transient Storage Support

Solidity Compiler v0.8.28 introduces high-level support for transient storage state variables of value types. JSON Yul ASTs generate on demand, reducing memory use. Standard JSON Interface now supports partial bytecode or IR requests. SMTChecker and Yul AST debug info bugs are fixed. USE_LD_GOLD option removed; CMAKE_CXX_FLAGS enables custom linkers. Contributors include Alexander Arlt, Anandu Raveendran, and Martin Blicha.
