Instead of compiling `solc` itself with CVC4 support, it is now enough to have `cvc5` executable on PATH when running the compiler. Instead of using API of CVC4, we now use SMT-LIB2 interface. That means we write the queries to temporary SMT-LIB2 files and call the solver process directly to run on the file.
