  1. SMTChecker: Upgrade CVC4 to cvc5 

    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.

  3. SMTChecker: Allow using multiple external solvers in one analysis 

    We are using SMTCommand inside UniversalCallback to call external
solvers on queries produced my our engines.

Previous mechanism set the external solver once during initialization
and it was not possible to change it later. This meant, that it would
not be possible to use, e.g., Eldarica and cvc5 at the same time.

Here we move the proper setup for SMTCommand just before we call it.
This setup is customized by subclasses of (CHC)SmtLib2Interface, which
call corresponding external solvers.
