  [analyzer] Produce SymbolCast symbols for integral types in SValBuilder::evalCast

Summary: Produce SymbolCast for integral types in `evalCast` function. Apply several simplification techniques while producing the symbols. Added a boolean option `handle-integral-cast-for-ranges` under `-analyzer-config` flag. Disabled the feature by default.
