Enable conditional expressions and switch statements in the CSEC machine

[AprupKale]

Enable switch statements to support code as follows:

public class Main {
    public static void main(String[] args) {
        int x = 2;
        String y;
        
        switch (x) {
            case 1:
                y = "One";
                break;
            case 2:
                y = "Two";
                break;
            case 3:
                y = "Three";
                break;
            default:
                y = "Default";
        }
    }
}

Enable conditional expressions to support code as follows:

int sign = x >= 0 ? 1 : -1;
